Which of the following demonstrates the Commutative Property of Multiplication? (3 points) 2(6a − 3) = (6a − 3) ⋅ 2 2(6a − 3)

Virty [35]

Commutative means 'you can swap them'. I.e., a+b = b+a, addition is commutative. Subtraction is not.

The first answer: 2(6a − 3) = (6a − 3) ⋅ 2 is an example where 2 and (6a-3) are the factors that can be swapped, because multiplication is commutative.

-Dominant- [34]

Answer:

Part A: $21 Part B: $30.21

Step-by-step explanation:

Part A: First, just multiply 15 to 40 divided by 100. 15 x 40/100

40/100= 0.4. 15 x 0.4=6. 15+6=$21

Part B: Discount the book by 25% and then add the sales tax which is 6% and then the answer would be $30.21.
