Unformatted text preview: Objective The student will be able to: use the distributive property to simplify expressions. SOL: A.3 Designed by Skip Tyler, Varina High School and Nicole Kessinger, Deep Run High School The Distributive Property The process of distributing the number on the outside of the parentheses to each term on the inside. a(b + c) = ab + ac and (b + c) a = ba + ca a(b - c) = ab - ac and (b - c) a = ba - ca Example #1 5(x + 7) 5 x + 5 7 5x + 35 Example #2 3(m - 4) 3 m - 3 4 3m - 12 Example #3-2(y + 3)-2 y + (-2) 3-2y + (-6)-2y - 6 Which statement demonstrates the distributive property incorrectly ? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 3 ( x + y z ) = a b c 5 2 1 6 k-4 8 0% 0% 0% 0% 1. 3(x + y + z) = 3x + 3y + 3z 2. (a + b) c = ac + bc 3. 5(2 + 3x) = 10 + 3x 4. 6(3k - 4) = 18k - 24 Answer Now A term is a 1) number, 2) variable, or 3) a product / quotient of numbers and variables....
