  1. 132 99 62 160 Bell Work 1. 62 + 132 + (–62) 22 + 49 + 28 3. 4. 5. 4 × 8 × 5

  2. The Distributive Property

  3. The Distributive Property The product of a and (b+c): a(b+c) = ab + ac ex: 5(x + 2) = 5(x) + 5(2) 5x + 10 The product of a and (b-c): a(b-c) = ab – ac ex: 4(x –7)= 4(x) – 4(7) 4x –28 Sharing what is Outsidethe parentheses with EVERYTHING INSIDE the parentheses.

  4. Find the total area of the rectangles.Area = length x width 6 ft 6 ft 20 ft + 4 ft

  5. Find the area of the rectangle.Area = length x width Find the area of each rectangle. 6 ft 6 ft 120 sq ft 24 sq ft 20 ft + 4 ft

  6. Find the area of the rectangle.Area = length x width Now put the two rectangles back together. 6 ft 120 sq ft + 24 sq ft 24 ft

  7. Find the area of the rectangle.Area = length x width 6 ft 144 sq ft 24 ft

  8. 4 x 2 x +2 A Visual Example of the Distributive property Find the area of this rectangle. We could say that this is 4(x + 2) Or..

  9. 4 2 4 x So we can say that 4(x+2) = 4x+8

  10. Example using the distributive property

  11. Another Example

  12. Another Example Or

  13. Another Example Or

  14. A swimming pool has a shallow end and a deep end. Find the surface area of the pool. Deep water 8 yds shallow water 5 yds 10 yds

  15. 40 + 80 = 120 square yards 40 80 8 yds 5 yds 10 yds

  16. Write an expression that shows two ways on how to find the area of the rectangle.(use the distributive property) 9 yds 5 yds 20 yds

  17. (9 x 5) + (9 x 20) = area 0r 9(5+20)=area 9 yds (9 x 5) (9 x 20) 5 yds 20 yds

  18. 1) Which of the following expressions shows the distributive property for 5(3 + 7)? (5 + 3) x (5 + 7) (5 x 3) x (5 x 7) (5 x 3) + (5 x 7)

  19. Which of the following expressions shows the distributive property for 3(9 + 4) ? (3 x 9) + (3 x 4) (3 + 9) + (3 + 4) (3 + 9) x (3 + 4)

  20. Which of the following expressions is equivalent to:2( 3) + 2( 3) 2 + 2 + 3 + 3 2 (3 + 3) 3(2 + 3)

  21. Which of the following expressions is equivalent to:(4 x 3) + (4 x 8) ? 3 x (4 + 8) 8 x (3 + 4) 4 x (3 + 8)

  22. Which of the following expressions is equivalent to:(5 x 9) – (5 x 3) ? 3 x (9 – 5) 5 x (9 – 3) 9 x (3 – 5)

  23. 11) Which expression is equivalent to 3(x + 7)? x + 10 x + 21 3x + 7 3x + 21

  24. 12) Which expression is equivalent to 4(x + 5)? x + 9 4x + 20 4x + 5 9x

  25. 13) Which expression is equivalent to 8(x – 2)? 10x 8x – 2 8x – 16 8x – 10

  26. Which expression is equivalent to 2(x – 3)? 2x – 6 2x – 5 2x – 3 2x – 2
