Answer:
X=-1
Step-by-step explanation:
0=2x+2
subtract 2 out
-2 = 2x
divide 2 on both sides x = -1
Use formula a squared equals to c squared minus b squared
40^2-24^2 is 1024
Square root of 1024 is 32.0
Step-by-step explanation:
Let A(x) be the area function of given rectangle.
Radius of circle = 7x
Therefore, length of rectangle = 14x
Width of rectangle = 7x

Let P(x) be the Perimeter function of given rectangle.
