Is 3(x + y) equal to 3x + y? Why or why not? What is the name ofthe rule that defines this operation (commutative, associative,distributive)? If a=18, b=2, and c=7, Does the expression a/b+c evaluate to 16 or to 2?Why (explain your answer)? Is this relationship correct? Why or why not?

1. 3(x+y) is not edaul to 3x + y. this is a distributive operation. 3(x+y)= 3x+3y
2. a/b+c= (18/2) + 7= 16 division is first then addition

The expression 3(x+y)=3x+y.
3 x + 3 y 3 x + y
No, the expressions do not equal each other. This is accordingto the distributive rule.
Given a=18, b=2, c=7.
= a b + c
= 18 2 + 7
= 18 9
=2
