Answer 2

Answer:

The answer is $27+8a$

Step-by-step explanation:

In order to determine the answer, we have to know about adding similar terms.

A term is basically a variable and its power. In an operation, we have to find all terms in order to add similar terms. We just add their coefficients.

In this case, we have two terms:

1. a
2. number

So, we add similar terms to simplify the expression:

$15+(12+8a)\\(15+12)+(8a)\\27+8a$

Finally the answer is $27+8a$
