Question

Which choice best represents the standard form representation of the following expression?1/3 (12 + 6x)A: 2 + -4xB: 2 + 4xC: 4 + -2xD: 4 + 2x

Answer 1

Given 1/3 (12 + 6x), the 1st step is to open the bracket;

`\begin{gathered} (1)/(3)(12+6x)=(12)/(3)+(6x)/(3) \\ =4+2x \end{gathered}`

So, the correct option is D: 4 + 2x
