NAME ___________________________________________________ DATE _____________________ PERIOD __________ Chapter Quiz Use the Distributive Property to write each expression as an equivalent expression. Then evaluate the expression. 2 (s + 20) 1. − 5 1. 2 2 2 −(s) + −(20); − s + 8 5 5 5 2. -6(12 - 8) -6(12) - 6(-8); -72 + 48 = -24 2. 3. Molly bought four rose bushes for $16.40 each. Use mental math to find the total cost of the bushes. Justify your answer by using the Distributive Property. $65.60; 4(16 + 0.4) → 64 3. + 1.6 = 65.6 Use the Distributive Property to write each expression as an equivalent algebraic expression. 1 4 1 4 −(8s) + − (16) 4. 5. 0.5(a - 6) 5. 0.5(a) + 0.5 (-6) 6. -2(r - 8) 6. -2(r) - 2(-8) 7. Carson is making up tool kits to give as holiday gifts. Each tool kit includes a $14 hammer, a $20 screwdriver, and a $6 measuring tape. Write two equivalent expressions for the total cost of 3 tool kits. Then find the total cost. 3(14 + 20 + 6); 7. 3(14) + 3(20) + 3(6); $120 Simplify each expression. Identify the coefficients and constants in each expression. 8. 4x + 9x - 4 - 7y 13x - 7y - 4; coefficients: 8. 13 and -7; constant: -4 9. 12z - 12g + 11g - 7z 9. 5z - g; coefficients: 5 and -1 Add or subtract. Use models if needed. 10. (7x + 8) + (-7x + 8) 10. 16 11. (-4x + 2) - (20x - 5) 11. -24x + 7 12. (x + 7) + (4x + 3) 12. 5x + 10 13. A rectangle has a length of (5x - 2) feet and a width of (4x + 7) feet. Write and simplify a linear expression for the perimeter. 2(5x - 2) + 2(4x + 7); 13.
