The Distributive Property INTEGRATED MATHEMATICS The Distributive Property Ex. 1) 5(x + 7) = 5x+35 Ex. 2) 3(m-4) 3m-12 9/6/2016 The Distributive Property Ex. 3)-2(y + 3) -24-6 Ex. 4)-3(2x-8) -6x+24 The Distributive Property Ex. 5) -l(y-5) -ly+5 Ex. 6)-6(2a-3b + 5c) -12a+186-30c Which Statement Demonstrates the Distributive Property Incorrectly? 1.3(x + y + z) = 3x + 3y + 3z 2. (a + b) c = ac + bc 3.5(2 + 3x) = 10 +3xX 4.6(3k-4) = 18k - 24 A term is a: 1) number, 2) variable, or 3) a product/ quotient of numbers and variables, Example: 5, m, 2x² 9/6/2016 Like Terms are terms with the same variable AND exponent. To simplify like terms, simply combine the like terms by adding the coefficients. Don't Change the Variables The Coefficient is the number in front of the variable. Examples 4a y2 5x 9/6/2016 Are these like terms? 1) 13k, 22k 2) 5ab, 4ba 4ab 3) x³, xX -2a 4x -15b 5x2 3y2 15 -6c 12b 10 12y2 Like Terms 7a 8c x2 -9y 4x 8y
