In order to simplify this expression, we need to use the Distributive Property:


\longrightarrow\tt{a(b+c)=ab+ac}

Where a, b, and c can be variables, constants, or a combination of the two.

Note: I'm unsure of whether or not you meant "3(4x+9)" or "3(4x-9)", but I am going to solve both.


\tt{3(4x+9)}

Multiply 3 times all the terms inside the parentheses:


\tt{12x+27}


\tt{3(4x-9)}


\tt{12x-27}

Answers:
\begin{cases}\tt{12x+27}\\\tt{12x-27} \end{cases}

I hope it helps you! Have an awesome day!

If you need any explanation or clarification, kindly let me know, and I will do my best to clarify your doubts! :D
