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

3. 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?

4. 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)

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

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

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

8. 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

9. 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)
