Question

What is the value of 9(4x - 4) when x = 5

Answer 1

Explanation:

9((4×5)-4)

9(20-4)

9(16)

144

Answer 2

144

Explanation:

plug in 5 where you see the x.

that gives us 9(4(5)-4)

multiply the 4 and the 5 first to get 9(20-4)

and by PEMDAS, we solve the parentheses first so now we have 9(16)

so now just multiply 9x16 to get 144
