Which of the following demonstrates the commutative property of multiplication?

3(4a − 2) = 12a − 6
3(4a − 2) = (4a − 2) ⋅ 3
12a − 6 = (4a − 2) ⋅ 3
(3 ⋅ 4a) − 2 = 3(4a − 2)

Step-by-step explanation:

Commutative property of multiplciation is

Here 3 is multiplied inside the parenthesis. Distributive property is applied.

is same as

Here, the terms 3 and 4a-2 are interchanged. So this equation demonstrates the commutative property of multiplication.

GCF 3 is factored out. factoring is applied.

Here 3 is not a common factor.
