use distributive property to simplify the expression.

Hi Karen,

Distributive property is meant by expanding and in algebra it means you should get rid of parenthesis before solving an expression.

**4 (c-2)**

**4 (c) - 4(2)**

**4c - 8 (Answer)**

**2 (3+d-1)**

**2(3) + 2(d) - 2(1)**

**6 + 2d - 2 subtract the like terms (6-2)**

**4 + 2d (Answer)**

**3 (w+1) - 1**

**3(w) + 3(1) - 1**

**3w + 3 - 1 subtract the like terms (3-1)**

**3w + 2 (Answer)**

hope it helps!
