Quizplus · Accepted Answer

The commutative property of addition allows us to change the order of the terms being added. Therefore, we can rewrite 9(m + n) as 9(n + m) and this is shown in choice B. The commutative property of addition states that changing the order of addends does not change the sum. Therefore, 9(m + n) is equivalent to 9(n + m), which is choice B.
