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`
