Question

(24.7C) The area of a rectangle is equal to x2 +

16x + 55 square units. If the length of the
rectangle is equal to x + 11 units, what expression
represents its width?

Answer 1

x + 5

Explanation:

A = LW

W = A/L

W = (x^2 + 16x + 55)/(x + 11)

W = [(x + 11)(x + 5)]/(x + 11)

W = x + 5
