The area (in square inches) of a rectangle is given by the polynomial function A(p) = p2 + 9p + 20. If the length of the rectang
boyakko [2]

Answer:

Width = p + 4

Step-by-step explanation:

Given

Area = p^2 + 9p + 20

Length = p + 5

Required

Determine the width

The area of a rectangle is:

Area = Length * Width

This gives:

p^2 + 9p + 20= (p+5)* Width

Expand

p^2 + 4p + 5p + 20= (p+5)* Width

Factorize

p(p + 4) + 5(p + 4)= (p+5)* Width

(p + 5) (p + 4)= (p+5)* Width

Divide both sides by p + 5

p + 4= Width

Width = p + 4
