Factor 9t–3u.
Write your answer as a product with a whole number greater than 1.
The factor of the expression 9t – 3u will be 3 and 3t – u.
What is factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
One of the many branches of mathematics is algebra. Algebra, which is a common thread throughout practically all of mathematics, is broadly defined as the study of numbers and symbols and the procedures for using these symbols in formulae.
The expression is given below.
⇒ 9t – 3u
Simplify the expression, then we have
⇒ 3·3t – 3u
⇒ 3(3t – u)
The factor of the expression 9t – 3u will be 3 and 3t – u.

13 Two sides of a triangle are 27 inches and 17 inches. What are the possible lengths of the third side? Give your answer as an inequality.
______
The third side of the triangle will be lies between 10 and 44
The rule that we will use to answer this is:
The sum of lengths of two sides of a triangle must be more than the length of the third side.
So, we have side lengths 27 and 17. 27 + 17 = 44 and thus the third side must be less than 44.
Now to consider how small it can be. If we represent the third side as X, we can get 17 + X > 44 which gives us X > 27
Therefore the third side is between, but not including, 10 and 44 units long.

What is a graph?A graph is a structure made up of a collection of things, where some object pairs are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.
Given data:
A certain model of a solar panel produces 1,200 KW of power for an area of one square meter,2,400 KW of power for an area of two square meters, and 3,600 KW of power for three square meters,
As you can see from the above, the power is linearly dependent on the area, and it can be seen by the following equation,
y = 1200x
Here, y = power and x = area,
Therefore, the amount of power y the solar panel can produce is linearly proportional to the size of x, the equation is y = 1200x, and the graph is attached below.

What percent of 16x is 4x?
4x is 25 percent of 16x.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Let the percentage be P.
Now,
P% of 16x = 4x
P/100 x 16x = 4x
P/100 = 4x/16x
P/100 = 1/4
P = 100/4
P = 25
This means,
25% of 16x is 4x.
We can cross-check.
= 25% of 16x
= 1/4 x 16x
= 4x
Thus,
25 percent of 16x is 4x.

The equivalent linear equation to the line 3x + 4y = 15 is the one in the first option:
y = (15 - 3x)/4
Which equation is equivalent to the given one?
Here we have the following linear equation:
3x + 4y = 15
And we want to find an equivalent linear equation where y is isolated in the left side of the equation. So let's isolate the variable.
If we subtract 3x in both sides of the linear equation we will get:
3x + 4y - 3x = 15 - 3x
4y = 15 - 3x
Now we can divide both sides by 4, so we will get:
4y/4 = (15 - 3x)/4
y = (15 - 3x)/4
This is the equation in option 1, so we conclude that the correct option is the first one.

The length of the mirror is [tex]3\frac{2}{33}[/tex] feet so it can fit into a wall of 4 feet.
What are the area and perimeter of a rectangle?We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.
We know the area of a rectangle is (length×width).
Given, The area of a rectangular mirror is [tex]10\frac{5}{6}[/tex] square feet.
The width of the mirror is [tex]2\frac{3}{4}[/tex] feet and assuming the length to be x feet.
∴ (11/4)×x = 65/6.
x = (65/6)×(4/11).
x = 260/66.

The complete table of values of the equation y = 3x + 5 is
x = -2, -1, 0, 1 2
y = -1 2 5 8 11
How to complete the table of values?The complete question is added at the end of this solution
From the question, we have the following equation that can be used in our computation:
y = 3x + 5
From the table of values added at the end of this question, we have the following x values
x = -2, -1, 0, 1 and 2
Substitute x = -2, -1, 0, 1 and 2 in y = 3x + 5
So, we have the following representation
y = 3(-2) + 5 = -1
y = 3(-1) + 5 = 2
y = 3(0) + 5 = 5
y = 3(1) + 5 = 8
y = 3(2) + 5 = 11
So, the complete table of values is

parenta=-1, h=k=0a=1, h=0, k=5a=1, h=5, k=-12a=-1, h=-5, k=-12Step-by-step explanation:
Given several transformed functions, you want to identify the parameters of the transformation: a, h, k.
TransformationWe assume your transformation of the function g(x) has the pattern ...
y = a·g(x -h) +k
You are trying to match the given functions with this pattern.
Here, 'a' is the multiplier of the absolute value function. In these examples, it is 1 or -1.
The parameter 'h' is the value subtracted from x inside the absolute value bars. (This is the amount of translation of the graph to the right.)
The parameter 'k' is the value added to the (scaled) absolute value, the constant on the right outside the absolute value bars. (This is the amount of translation of the graph upward.
parent: a=1, h=k=0a=-1, h=k=0a=1, h=0, k=5a=1, h=5, k=-12a=-1, h=-5, k=-12__
Additional comment
We have used g(x) as the function name, instead of the more usual f(x). This is because Brainly squawks any expression where f(x) is multiplied by 'a'.
Once you have identified the parent function, the pattern matching process can begin. The value of 'a' multiplies the function. The value of 'k' is added to the function. The value 'h' is subtracted from x where x is inserted into the parent function.
If the parent function is y = (3x²+2), then h=1 would give y = (3(x-1)²+2). The value of 'a' would multiply this expression, and the value of 'k' would be added to this expression.

Men's heights are normally distributed with a mean of 69.0 inches and a standard deviation of 2.8 inches, while women's heights are normally distributed with a mean of 63.6 inches and a standard deviation of 2.5 inches.
(a) What percentage of men must duck when walking through a door that is 72 inches high?
(b) What percentage of women must duck when walking through a door that is 70 inches high?
(c) What door height would allow at least 95% of men to walk through the door without ducking?
Approximately 95% of men must duck when walking through a door that is 72 inches high. Approximately 5% of women must duck when walking through the door. The door height that would allow at least 95% of men to walk through the door without ducking is 74 inches.
The mean height of men is 69.0 inches and the standard deviation is 2.8 inches, while the mean height of women is 63.6 inches and the standard deviation is 2.5 inches.
(a) To find the percentage of men who must duck when walking through a door that is 72 inches high, we first need to find the percentage of men whose height is less than 72 inches.
The height of the door is 72 inches, which is 3 inches above the mean height of men.
Since the standard deviation is 2.8 inches, this means that approximately 95% of men are within 2.8 * 2 = 5.6 inches of the mean height.
Therefore, approximately 95% of men are between 69.0 - 5.6 = 63.4 inches and 69.0 + 5.6 = 74.6 inches tall.
If the height of the door is 72 inches, approximately 95% of men must duck when walking through the door.
(b) To find the percentage of women who must duck when walking through a door that is 70 inches high, we first need to find the percentage of women whose height is less than 70 inches.
The height of the door is 70 inches, which is 6.4 inches above the mean height of women.
Since the standard deviation is 2.5 inches, this means that approximately 95% of women are within 2.5 * 2 = 5 inches of the mean height. Therefore, approximately 95% of women are between 63.6 - 5 = 58.6 inches and 63.6 + 5 = 68.6 inches tall.
If the height of the door is 70 inches, approximately 5% of women must duck when walking through the door.
(c) To find the door height that would allow at least 95% of men to walk through the door without ducking, we need to find the height that is within 2 standard deviations of the mean height of men.
Since the standard deviation is 2.8 inches, this means that approximately 95% of men are within 2.8 * 2 = 5.6 inches of the mean height.
Therefore, the door height that would allow at least 95% of men to walk through the door without ducking is 69.0 + 5.6 = 74
