Question 78791: 3(x+2)+5x
Answer by mathdoc314(58)   (Show Source): You can put this solution on YOUR website!

Distributive Law: a(b+c) = ab + ac
Associative Law: (a+b)+c = a+(b+c)
Commutative Law: a*b = b*a 

3(x+2)+5x = (3x + 6) + 5x (distributive law)
          = (3x + 5x) + 6 (associative law)
          = (3+5)x + 6    (distributive law)
          = 8x

I don't see that the commutative law is used here.
