Step-by-step explanation:
Let the width be x feet.
Therefore, length = 2x - 10
Perimeter of rectangle = 52

What you help with exactly?
Look at the table and find the X value for when both f(x) and g(x) are the same,
They are the same when X is -1 and when x is 0
The two answers would be X = -1 and x = 0
