# How do you multiply -w+4(w+3)?

Jul 29, 2016

Use the distributive property and then combine like terms.

#### Explanation:

The distributive property states that a(b+c)=a⋅b+a⋅c. Let's use this to solve our problem:

$4 \left(w + 3\right) = 4 \cdot w + 4 \cdot 3 = 4 w + 12$

We now have $- w + 4 w + 12$.

Next, combine like terms to get $3 w + 12$.
