Question 16726: ok I am having some trouble on "finishing" the product of some Distributive properties ok, for equation -9(3x + 8) I put down the following steps:
= -9*3x + -9*8
= -27x + -72 (final answer) I am not sure if this is correct or not.
My other question on the same topic is an equation i did like so:

5(x + 1)
= 5*x + 5*1
= 5x + 5 (final answer) please let me know if i am doing the distibutive property correctly.
