Question

Mrs. Aldridge spilled coffee on her Answer Key and can't see the width of

the rectangle anymore. What would be the width of a rectangle with the
given area (shown in image below)?
x +9
x² + 11x + 18

(My answer is a guess so please show your work if you answer this question!)

thank you:)

Answer 1

x + 2

Explanation:

Area = x² + 11x + 18

length = x + 9

width = ?

Area = length x width

Factor the polynomial x² + 11x + 18:

length x width = (x + 9)(x + 2) = x² + 11x + 18

The length is x + 9, therefore the width is x + 2
