The problem you provided is an example of the associative property of addition.

To understand why this is the case, let's first define the properties in question:

1. Commutative Property: This property states that the order of the numbers being added or multiplied does not affect the result. In other words, you can add or multiply numbers in any order, and the sum or product will remain the same.

2. Associative Property: This property states that the grouping of numbers being added or multiplied does not affect the result. In other words, you can change the grouping of numbers being added or multiplied, and the sum or product will remain the same.

3. Distributive Property: This property states that multiplying a number by a sum or difference is the same as multiplying the number by each term in the sum or difference and then adding or subtracting the results.

In the given problem, we have (2 + a) + 7 = 2 + (a + 7).

Using the associative property of addition, we can rearrange the grouping of the terms within the parentheses without changing the result. So, the left side of the equation can be written as 2 + (a + 7).

Since the left side of the equation is equal to the right side of the equation, we can conclude that this is an example of the associative property of addition.
