Question

2x + 3(x +3) + (x + 6)

Answer 1

For this case we must simplify the following expression:

$2x + 3 (x + 3) + (x + 6)$

We apply distributive property to the terms within parentheses:

$2x + 3x + 9 + x + 6 =$

We add similar terms:

$2x + 3x + x + 9 + 6 =\\6x + 15$

Thus, the simplified expression is: $6x + 15$

Answer:

$6x + 15$
