Question

Which expression is equal to (2x + 5) · 8 using the commutative property?
A. (5 + 2x) · 8
B. 8 · 2x + 5 · 8
C. 2x + (5 · 8)
D. (2x + 5 · 8)

Answer 1

@~Jess, Which one do you believe is correct?

Answer 2

C

Answer 3

Actually, this might be a trick question for you. They want the commutative property of addition. In algebra, whatever manipulation you do has to be equal to the original expression.

In this case
\[(2x+5)⋅8≠2x+(5⋅8)\]


So C cannot be correct.

Answer 7

You know that it's NOT A? What process of logic led you to eliminate A as an answer choice?

Answer 8

My friend

Answer 9

I see, but this is a trick question. They want the commutative property of addition in this case. The goal is to eliminate the expressions that are not equal to the original expression, and then proceed from there.
