In this case, we'll have to carry out several steps to find the solution.
Step 01:
perimeter = ?
x + 4 = width
2x - 3 = length
Step 02:
perimeter = 2* width + 2*lenght
perimeter = 2 * (x + 4) + 2 * (2x -3)

Answers
The greatest common factor(gcf) of the given expression is 3xy.
The expression is 6x²y - 12xy + 9x³y².
From all the terms we take the coefficients. 6 ,12 and 9
The GCF of these three numbers is 3 as it divides all the three numbers.
Now for the variable x. the lowest power will be the gcf. Hence the gcf will have x.
Now for the variable y. the lowest power will be the gcf. Hence the gcf will have y.
Therefore the gcf of the given expression will be 3xy .
6x²y - 12xy + 9x³y² = 3xy (2x - 4 + 3x²y)
The HCF, or highest common factor, is the largest number that divides each of the two or more numbers. HCF is also known by the titles The Greatest Common Measure (GCM) and The Greatest Common Divisor (GCD).
The smallest common multiple of any two or more numbers is found using the least common multiple, or LCM. There are two distinct methods: LCM and HCM. The HCF of two numbers is the highest factor that will exactly any divide two integers equally.

Using the equation of slope intercept form, the equation of the given graph is y=x-3.
In the given question we have to find equation of the given graph.
From the given graph the points are (3,0) and (0,-3).
We know the standrd equation of the line is y=mx+c
where m=slope and c=value of y at the y intercept form.
So the value of c= -3
Now finding the value of m.
m={y(2)-y(1)}/{x(2)-x(1)}
From the points, x(1)=3, x(2)=0, y(1)=0, y(2)= -3
Putting the value
m=(-3-0)/(0-3)
m=-3/-3
m=1
Now putting the value of m and c in the equation
y=mx+c
y=1*x+(-3)
y=x-3
Hence, the equation of the given graph is y=x-3.

When you're graphing a function, and its inverse, there is a table where you list the x and y factors. I know how you're supposed to solve for the y coordinate, by plugging in the x factor into the function and solving it for y. However, how do you know what your x factors are going to be?
Answers
Step-by-step explanation:
We want to identify how to determine the x-factors for the graph of a function.
On some occasions, the x values for the function will be provided for you to solve for the y values. but on other occasions, the x values are not provided and you have to decide them yourself.
For a linear function, most times, you can pick values within any range of values, e.g from 0 to 5, or 2, 4, 6, 8, 10. Since it is a linear function, it will eventually result in a straight line that contains all other points.
For a quadratic function, the best practice is to pick points around the vertex of the function. The vertex of a function is either the minimum or maximum point of the function.
For example, if the vertex of a quadratic function is (4, 10), the x-coordinate of the vertex is 4. To pick your points, pick points that are some values below 4 and some values above 4, like 2, 3, 4, 5, 6 or 0, 2, 4, 6, 8 That way, you get points that are on either side of the vertex and that will make your plot easier.

We have to find the probability of spinning a 4 on the spinner
So, the probability of spinning a 4 is,
Probability = (Area of sector having number 4)/(Area of the circle)
Probability = (30°/360°×π×r²)/(π×r²)
Probability = 1/12

The student council sold two types of ice cream, sundaes and cones, during homecoming week. Each sundaes cost the same amount, and each cones cost the same amount.
One the first day they earned $210 for selling 125 cones and 10 sundaes
One the second day they earned $256 for selling 100 cones and 30 sundaes.
What was the cost in dollars for each cone sold by the student council?
Answers
Answer:
1 cone = $1.36
Step-by-step explanation:
125 c + 10 s = $210
100 c + 30 s = $256
make one of the terms the same (easier one = 30 sundaes)
125 × 3 = 375 c
10 × 3 = 30 s
210 × 3 = $630
375 c + 30 s = $630
375 c + 30 s = $630
100 c + 30 s = $256
same sign = subtract
375 - 100 = 275 c
30 - 30 = 0 s
630 - 256 = $374
275 c = $374
÷ 275 on both sides to get c
c = $1.36

We need to find the area of the sector which is given by the next formula:

First, we need to find the area of the circle:
[tex]\begin{gathered} A_c=\pi\ast r^2 \\ Replacing \\ A_c=\left(12\right)^2\pi \\ A_c=144\pi \end{gathered}[/tex]Now, we can use the formula for the area of the sector

Area of the sector = 128π/5
Area of the sector = 80.42477

Recall that:
Distributive property : a(b+c) = ab + acLike terms are terms with the same variable(usually defined by a letter) and same exponent. E.g. 4x² and 9x² are like terms because they both have a variable of x and an exponent of 2. Because they are like terms they can be combined to make 13x². This idea was used to combine (4b and 5b) and (16 and -30)Answer:

Step-by-step explanation:
Given expression,

Let's simplify the expression,

→ 4b + 16 + 5b - 30
→ (4b + 5b) + (16 - 30)
