Question

Which pair of expressions is equivalent using the Associative Property of Multiplication? (3 points)

4(2a ⋅ 5) = (4 ⋅ 2a) ⋅ 5
4(2a ⋅ 5) = 8a ⋅ 20
4(2a ⋅ 5) = (2a ⋅ 5) ⋅ 4
4(2a ⋅ 5) = 4 ⋅ 2a ⋅ 5

Answer 1

Well the associative property is re-ordering the parenthesis and in the 1st one you move the parentheses to the back 2 variables so it would be that one.

Answer 2

Because in all 3 of the other ones you manipulate the numbers one way or another too.
