Question

Which pair of expressions is equivalent using the Associative Property of Multiplication?

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

The third answer, 4(2a • 5) = (2a • 5)4.
When fully distributed, both give the answer 8a • 20 making them equivalent through Associative Property.
