Write the difference in factored form. (24x4 - 15x2 + 6x) - (10x4 + 5x2 - 4x)
Answer:
The factored difference is: [tex]2x(7x^3 - 10x + 5)[/tex]
Step-by-step explanation:
Difference in non factored form:
To find the difference in non-factored form, we subtract the common terms. So
[tex]24x^4 - 15x^2 + 6x - (10x^4 + 5x^2 - 4x) = 24x^4 - 10x^4 - 15x^2 - 5x^2 + 6x + 4x = 14x^4 - 20x^2 + 10x[/tex]
Greatest common factor:
Of the exponents: Between [tex]x^4, x^2[/tex] and [tex]x[/tex], it is the one with the lowest exponent, so x.
Between 14, 20 and 10:
14 - 20 - 10|2
7 - 10 - 5
So 2
The gcf is 2x, which means that the factored expression is:
[tex]2x(\frac{14x^4}{2x} - \frac{20x^2}{2x} + \frac{10x}{2x}) = 2x(7x^3 - 10x + 5)[/tex]
The factored difference is: [tex]2x(7x^3 - 10x + 5)[/tex]

x-8= -12 what is x in the equation
Answer:
-4
Step-by-step explanation:
Answer:
x = -4
Step-by-step explanation:
Isolate the variable x
x - 8 = -12
To isolate the variable, add 8 to both sides (this cancels the 8 out on the left side)
x - 8 + 8 = -12 + 8
x + 0 = -4
x = -4
Reggie is making a double layer cake the recipe for the first layer calls for 2 1/4 cups sugar. the recipe for the second layer calls for 1 1/4 cups of sugar. Reggie has 5 cups of sugar. How much will he have left after making both recipes?
Answer:
Step-by-step explanation:
Meg, add the fractions
2_1/4 + 1_1/4
or 2 + 1 + _1/4 + _1/4
3 + _2/4
3 + _1/2
3_1/2
then what's left is
5 - 3_1/3 = 1_1/2

If the sum of two numbers is 10 and the diffference is 6, find the numbers
X + y = 10
Rewrite as y = 10-x
Y - x = 6
Replace y
10-x -x = 6
Simplify:
10-2x = 6
Subtract 10 from both sides:
-2x = -4
Divide both sides by -2:
X = 2
Now replace x in the first equation:
2 + y = 10
Subtract 2 from both sides:
Y = 8
The two numbers are 8 and 2

Kathy has 8 feet of ribbon. How many inches of ribbon does she have?
Isabella’s room is 4 yards wide. How many feet wide is her room?
Answer:
96 inches, and 12 feet
Step-by-step explanation:
There are 12 inches in every foot, so I multiplied 8 times 12, which is 96. Then, there are 3 feet in every yard, so I multiplied 4 times 3, which is 12. I hope this helps :)
Martin says that 1/3 + 1/6=2/9 Use the drop-down menus to explain why Martin is incorrect. Martin is incorrect because is incorrect
Answer:
A. is incorrect. He has to divide 76 by 19, instead of subtracting 19 to 76.
B. This equation has one solution. v=4
Step-by-step explanation:
Hi, Martin’s answer is incorrect.
A. He has to divide 76 by 19, instead of subtract 19 to 76.
The correct steps are:
19v = 76
Since 19 is multiplying the variable, to eliminate it we have to divide by 19.
v = 76/19
v = 4
B. This equation has one solution. It’s v=4

Answer: infinitely many solutions
Step-by-step explanation:
3x + 4y = -5 ... 1
6x + 8y = -10 ... 2
Take the second equation and divide by 2
3x + 4y = -10
As you can see, the two equations are exactly the same
So they have infinite solutions

From a collection of 52 store customers, 3 are to be chosen to receive a special gift. How many groups of 3 customers are possible?
Answer:
132,600 possibilities
Step-by-step explanation:
The first one chosen can be 1 of 52
The 2nd one chosen is 1 out 51
And the 3rd chosen is 1 out 50
So...
52 x 51 x 50 = 132,600
There are 22,100 groups of 3 customers that are possible from the given collection of 52 store customers.
What is a combination?It is an arrangement of a set of numbers from a total set where the order of the set is not relevant.
We have,
The number of groups of 3 customers that can be chosen from a collection of 52 store customers can be calculated using the combination formula:
nCr = n! / r!(n - r)!
where n is the total number of customers (52) and r is the number of customers chosen (3).
Substituting the values, we get:
52C3 = 52! / 3!(52 - 3)!
52C3 = 52! / 3!49!
52C3 = (52 × 51 × 50) / (3 × 2 × 1)
52C3 = 22,100
Therefore,
There are 22,100 groups of 3 customers that are possible from the given collection of 52 store customers.

Answer:
18 grids for each side
have a nice day ^_^
Answer:
8.0 represents how many squares there are on one side but that will measure to be 4mm on each side. We need to make it 9mm on each side by making the processor bigger and adding 5mm.
½=0.5 and thats 1 square.
Expand each side by 10 and that'll make the processor 9mm.
A sample of 100 cars driving on a freeway during a morning commute was drawn, and the number of occupants in each car was recorded. The results were as follows: NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Occupants 1 2 3 4 5 Number of Cars 64 19 12 3 2 Find the sample median number of occupants.
Answer:
The sample median number of occupants is 1.
Step-by-step explanation:
Median:
The measure that separates the lower half of the distribution from the upper half.
In this question:
Total of 100 cars.
64 have 1 occupant.
19 have 2 occupants
12 have 3 occupants
3 have 4 occupants
2 have 5 occupants.
Median:
In the cumulative distribution
100/2 = 50
While we count until 64, it has 1 occupant, so 50 is one occupant, which means that the sample median is 1.
The sample median number of occupants is 1.

What is the volume of a cylinder, in cubic inches, with a height of 13 inches and a
base diameter of 12 inches? Round to the nearest tenths place
Answer:
Rounded to the nearest integer, the volume of the cylinder is 5,878 cubic inches.
Step-by-step explanation:
Given that the volume of a cylinder is calculated using the formula Phi x Radius ^ 2 x Height, and knowing that the cylinder in question has a height of 13 inches and a base diameter of 12 inches, to calculate said volume the following calculation must be done:
Phi x (12x12) x 13 = X
Phi x 144 x 13 = X
Phi x 1,872 = X
3.14 x 1,872 = X
5,878.08 = X
Thus, rounded to the nearest integer, the volume of the cylinder is 5,878 cubic inches.
The answer is 1470.3
