For this case we must simplify the following expression:
[tex]2x + 3 (x + 3) + (x + 6)[/tex]
We apply distributive property to the terms within parentheses:
[tex]2x + 3x + 9 + x + 6 =[/tex]
We add similar terms:
[tex]2x + 3x + x + 9 + 6 =\\6x + 15[/tex]
Thus, the simplified expression is: [tex]6x + 15[/tex]
Answer:
[tex]6x + 15[/tex]
