2. Section 1.7 A

3.  TSWBAT use the distributive property to simplify expressions.

4.  Distributive Property

5. Distributive Property: for every real number a, b, and c: 1. a(b + c) = ab +ac = (b + c)a 2.a(b – c) = ab – ac = (b – c)a

6. Use the distributive property to simplify each expression. 1. 3(x + 6)2. (3n – 5)(-2) 3. -9(2x + 7)4. (15y – 25)( 1 / 5 ) Example 1

7. Solve each by using the distributive property. 2. Find the cost of 3 t-shirts that cost $8.95 each. 1. Find the total cost of 4 CDs that cost $12.99 each. Example 2

8.  Rewrite as a sum or difference.
