Quizplus · Accepted Answer

The commutative property of addition tells us that the order in which we add two numbers doesn't matter. That means 9 + x is the same as x + 9. Thus, B is the correct choice because it's the only one that matches this format. By commutative property of addition, we can rearrange the order of the terms. So, 9 + x is equivalent to x + 9.
