Answer 3

Find the answers that use multiplication. Which are they?

Answer 4

is it d

Answer 5

The answer would be D

Answer 6

why do you think it's D?

Answer 7

c

Answer 8

It would be D because you have 3n (any # with a variable next to it means mutilply them) and then you have -8 which would decrease 3n

Answer 9

C and D both use multiplication. Now it says 3 times a number decreased by 8. It's between those two answers. C states n-8 times 3, because you always work the parenthesis first. Can you tell me what D states?
