Asked by Sammy

I have no idea how to do this problem:
Select the expression below that is equal to 4(9-m).
A. 4m-36
B. 13-m
C. 36-m
D. 36-4m
Answered by Ms. Sue
4(9-m) = 36 - 4m

Multiply both terms in parentheses by 4.

Okay I get it now. Thank you so much!

I think in simple terms you are removing the parenthesis, so you need to multiply 4 by each one inside the parenthesis, 4x9=36, and 4x-m=-4m so I believe tat "D" sis the answer.
