Using the Distributive Property 3L interpret complicated expressions by viewing one or more of their parts as a single entity

Distributive Property The Distributive Property is an algebraic property which is used to multiply a single term and 2 or more terms inside a set of parentheses. Example 1: 3(x + 6) = 3(x) +3(6) How would I simplify this expression after I distributed?

Practice 1. What is wrong here? 4(y + 3) = 4y + 3 2. (y + 7)y 3. 0.5n(n – 9) 4. (2 – n)(2/3)

Example 2 Simplify the expression: 4(n+9) – 3(2 +n) What did you do first and why?

Practice Simplify the expression: 5. (4a – 1)2 + a 6. -6(v + 1) + v

Example 3 Find the perimeter and area of the rectangle: 5 v + 3

Practice 7. Find the perimeter and area of the rectangle. P = 2L + 2W P = 2(8-12w) + 2(9) P = 16 – 24w + 18 P = 34 – 24w A = L x W A = 9(8 – 12w) A = 72 – 108w 7. 9 8 – 12w

Challenge! Translate the verbal phrase into an expression then simplify. 1. Twice the sum of 6 and x, increased by 5 less than x. 2(6+x) + (x-5) 2. Three times the difference of x and 2, decreased by the sum of x and 10. 3(x-2) – (x+10)
