Lesson 5.2 Perimeter / area
Obj: to calculate Perimeter + area on a coordinate plane Rectangle P = 2L + 2W A = L x W Square P = 4 x S A = S 2
Lesson 5.3 Distributive Property (1 to every term)
Obj: To distribute over addition + subtraction. Distributive Property Rules a (b + c) = ab + ac (b + c) a = ab + ac a (b – c) = ab - ac
Example 1: order of operation 6 (6) 36 6 (2 + 4)
Example 2: Distributive Property 4 (3y 2) 12y + 8
Example 3 2x (3yz + 7a + 9b 12) 6xyz + 14ax + 18bx 24x
Example 4 3 ( 2x 4y + 3) 6x + 12y 9
