1. Using Formulas Distributive Property LESSON 41POWER UP IPAGE 296

2. Formulas: Perimeter Write a formula for perimeter of a rectangle by doubling the length, doubling the width, and then adding the two numbers. P = 2l + 2W l w

3. Formulas: Perimeter Write a formula for perimeter of a rectangle by adding the length and width, then doubling that number. P = 2(l + w) l w

4. Formulas: Perimeter Use the two perimeter formulas to find the perimeter of this rectangle. 5 cm 2cm

5. Distributive Property Distributive Property of Multiplication Over Addition Multiply the terms being added or subtracted inside parentheses by the term on the outside of parentheses. a(b + c) = a( b – c) =

6. Distributive Property 2(l + w) = 5(10 + 4) = 3(a +4) = 6(y – 5) =

7. Distributive Property m(n + p) = w(2 – x) =

8. Distributive Property Show two ways to simplify this expression: 3(4 – 1) Simplify 6(z + 3). Show and justify the steps.
