Math Problem Statement
Solution
The goal is to identify the property that justifies the second step of the two-column proof, which involves changing the order of terms in the given expression.
Here’s a breakdown of the first two steps:
- Given Expression:
- Rewriting Terms:
This step involves rearranging the terms, specifically switching the position of and .
Justification:
The property that allows us to rearrange the terms in addition is the Commutative Property of Addition. This property states that the order of terms in an addition operation can be changed without affecting the sum.
Answer:
c. Commutative Property of Addition
