answer
B. x = - 9 and x =5
Hello!

You can break up both of the expressions

4x + 36 = 0

Subtract 36 from both sides

4x = -36

Divide both sides by 4

x = -9
------------------------------------------------------------------------------------------------------
8x - 40 = 0

Add 40 to both sides

8x = 40

Divide both sides by 8

x = 5

The answer is B) x = -9 and x = 5

Hope this helps!
