How do you simplify 3(x+4)?

Apr 27, 2016

Use the distributive property to get
$\textcolor{w h i t e}{\text{XXX}} 3 \left(x + 4\right) = \textcolor{b l u e}{3 x + 12}$

Explanation:

The distributive property tells us that
$\textcolor{w h i t e}{\text{XXX}} a \times \left(b + c\right) = \left(a \times b\right) + \left(a \times c\right)$

Therefore
$\textcolor{w h i t e}{\text{XXX}} 3 \left(x + 4\right) = \left(3 \times x\right) + \left(3 \times 4\right) = 3 x + 12$
