Answer:

Step-by-step explanation:

Perimeter of a rectangle is
2*width + 2*length
then multiply the perimeter by the cost per foot
2*(150ft) + 2*(200ft)
300ft + 400ft
700ft
700ft * $10/ft
$7000

Since we are solving the quadratic equation because the highest degree in the equation is second. We arrange in the form of ax²+bx+c = 0.

Combine like terms.

Solve the equation by factoring.

Hence the values of x that make f(x) = g(x) are -3 and 1.
