1.To simplify, distribute a to 8 and to 7.

2.8(a) can be rewritten as 8a.

3.8 (a + 7) can be rewritten as 8 (a) + 8 (7).

4.8 (a + 7) can be rewritten as 8 (a) + (7).

5.An equivalent expression is 15a.

6.An equivalent expression is 8 a + 7

7.An equivalent expression is 8 a + 56

Option 3)

8(a + 7) can be rewritten as 8(a) + 8(7).

Option 7)

An equivalent expression is 8a + 56

Step-by-step explanation:

We are given the following expression:

We can simplify the expression by distributing 8 over (a+7).

Distributive property:

Simplifying the expression, we get,

Thus, the correct options are:

Option 3)
