Answer 9

So, your not going to try it?

Answer 10

well what am i supposed to do?

Answer 11

C.

Answer 12

Are you saying you've never heard of the distributive property?

This one: a(b+c) = ab + ac

Answer 13

no

Answer 14

i know a+b=b+a

Answer 15

That's the commutative property. Good.

a(bc) = (ab)c -- is associative. That also works for addition.

Answer 16

BTW - C is not correct. Not sure what dakid88 was doing. I got one gloriously wrong, yesterday. It happens.

Answer 17

So, apply this principle

a(b+c) = ab + ac

to your problem

u • 5 + u • v

What do you get?
