Question

Find the area of the shaded region. Write your answer in factored form.

Answer 1

6x+ 21

Explanation:

Find the area of the whole thing

find the are of the small shape

minus this from the whole thing

whole thing = (x+5)(x+5) = x^2+ 2x+ 25

small = (x-2)(x-2) = x^2 -4x +4

(x^2+ 2x+ 25)-(x^2 -4x +4)= 6x+ 21
