9x + 7

Step-by-step explanation:

5x + 4x = 9x

2 + 5 = 7

Therefore, the answer is 9x + 7.

Check:

Plug in a number into the equation. For example, :

(5(2)+2) + (4(2)+5) = (10+2) + (8+5) = 12 + 13 = 25

Plug in the same number into 9x+7 to see if you get the same number.

9(2) + 7 = 18 + 7 = 25

the answer is d. 75%
