You need to work backwards
if it is no more than 9 units away from 8
thus x must be 8-9<x<8+9 solving -1<x<17
so the answer is 4.
Answer:

Can only be simplified through calculator using decimal equivalents.
Step-by-step explanation:
The perimeter of a rectangle is the formula P=2l+2w. Here
and
. So the perimeter is:

Answer:
1. 208 in^2
Step-by-step explanation:
1. We can break the shape up into a rectangle in the middle and 2 triangles on either side of said rectangle.
The dimensions of the rectangle are 8 in by 20 in, and we only know one leg of the triangle as well as the hypotenuse.
If we know one leg and the hypotenuse we can use the pythagorean theormed to sovle for the other side and get 6 in.
So we have
(8 * 20) + 2((1/2)(6)(8))
160 + 48
208 in^2
The slope is 2 and the y intercept is 3 m = 3 and b = 2x
