Question 832169: Which equation below shows the distributive property for addition or multiplication? The diagram below could be useful model which of the following?
A) a+(b+c) = (a+b)+c
B) 191+18+9=(191+9)+18
C) 15 x (3+5) = 15x3+15x5
D) 11+17+9+13=(11+9)+(17+13)

The distributive property is exactly (C)
.
15x(3+5)
you could solve this by adding the 3 and 5 together to get 8. But you don't always have like terms. What if it was 15x(3y+5)? Then the distributive property would help a lot.
First, you would have 15x * 3 and then 15x * 5. You'll get the same answer.
