Step-by-step explanation:

Hint:

a² - 9a + 15 = (a-7)(a-2)

a² + 9a + 15 = (a+7)(a+2)

a² + 3a - 10 = (a-2)(a+5)

a² + 5a - 14 = (a-2)(a+7)

a² - 5a - 14 = (a-7)(a+2)

What is the area of this figure? Enter your answer in the box.

earnstyle [38]

To find the area you do base times height. Base is the number across,and height is the number that is up and down.So in this case you will multiply 9 and 5 and 9 and 7 and get 45 and 72.Then you will add 45 and 72 together and get 117. So the area is 117. Answer 117. Hope this helps :D.
