Enter your answer in the box.

Answers

Answer:

450

Step-by-step explanation:

Formula = Number x 100

What is area of triangle?

The area of the triangle is half of the product of base and height of the triangle. It can be calculated as,

Here, b is the length of base, and h is the height.

Tony's architecture firm is constructing a square pyramid play structure for a school.

The length of one side of the base will be 9 feet, Each face is a triangle with a height of 8 feet. The pyramid will be open at the bottom and not covered.

As the height of the triangle is 8 and base is 9 feet of triangle. Thus, the area of one triangular face is,

[tex]A=\dfrac{1}{2}\times9\times8\\A=36\rm\; ft^2[/tex]

Area of 4 triangle side is,

[tex]A=36\times4\\A=144\rm\; ft^2[/tex]

just sub the x in the equations with each of the given x numbers
Ok it’s pretty easy!

Under the X, that’s what we call a input! And I’ll take the equation from number 11
(X-5)

Under the X we see numbers like (-4, 8, 1, 3, 4)

What we do here is we grab our equation (x-5) and we exchanged “X” for one of the numbers, I’ll use the first example! Which is (-4)

So our equation will look like this
(-4 - 5) and what you do know is solve it which will give you the answer of “-9”

So now what you do is put negative nine as the y for that column and bam!
