Question

Simplify.3(x+4)A. 12 xB. 7xC. 3x+12D. 3(x+4)

Answer 1

Given the expression:

`3\left(x+4\right)`

To simplify the expression you have to distribute the multiplication on the parentheses term, that is, multiply each term inside the parentheses by 3:

`\begin{gathered} 3\left(x+4\right) \\ 3*x+3*4 \\ 3x+12 \end{gathered}`

The simplified expression is 3x+12
