1. The document discusses the distributive property in algebraic expressions. 2. The distributive property allows expressions to be simplified by distributing numbers or variables being multiplied across groupings. 3. Examples show distributing numbers or variables across terms in parentheses, such as 4(3x + 5) being simplified to 12x + 20.

1. Agenda Monday, September 21 1. 1-7 Distributive Property 2. Homework 8 p. 50 # 15 - 41 odds, 55, 57, 59

2. p. 41

4. Distributive Property Which is easier to do? 3(20 + 8) = 3 * 28 or 3(20 + 8) = 3*20 + 3*8

5. 4 times the quantity of 3x + 5 Distributive Property is used to simplify algebraic expressions. An algebraic expression in simplest form has no grouping symbols. 4(3x + 5) 4(3x + 5) 4(3x) + 4(5) 12x + 20 Distribute "times 4" to each item in parenthesis.

7. 6( m + 5) 2(3 - 7t) (0.4 + 1.1c)(3) Check Understanding 3 p. 48

8. Tricky ones: -5 can also mean -1(5) so... -(4n + 6) means -1(4n + 6) -1(4n) + -1(6) -4n - 6

9. Check Understanding 4 p. 48 a. -(2x + 1) b. -(7 - 5b) c. (3 - 8a)(-1)
