  1. The Distributive Property Day 2

  2. Find the total area of the rectangles using two different expressions 5ft 5ft 10 ft + 4 ft

  3. One Way: 5(10) +5(4) Find the area of each rectangle. 5ft 5ft 50 ft2 20 ft2 10 ft + 4 ft

  4. 5(10) +5(4) 50 +20 = 70 Now put the two rectangles back together. 5ft 50 sqft + 20 sqft 14 ft

  5. Second way: 5(10+4) 5(14) = 70ft2 5ft 70 ft2 10 + 4 ft =14 ft

  18. Now we will use the distributive property first, then combine like terms second.

  19. 1. Simplify 6(5 + n) – 2n. 6(5 + n) – 2n 6(5) +6(n) – 2n Distributive Property. 30 + 6n – 2n Multiply. 30 + 4n Combine coefficients 6 – 2 = 4.

  20. 2. Simplify 3(c + 7) – c. 3(c + 7) – c 3(c) +3(7) – c Distributive Property. 3c + 21– c Multiply. 2c + 21 Combine coefficients 3 – 1 = 2.

  21. Simplify. 3. 4(3x + 6)  7x 4(3x) + 4(6) – 7x Distributive Property. 12x + 24 – 7x Multiply. 5x + 24 Combine coefficients 12 - 7 = 5. 4. 6(x + 5) + 3x 6(x) + 6(5) +3x Distributive Property. 6x + 30 +3x Multiply. 9x + 30 Combine coefficients 6 + 3 = 9.

  22. Make sure to practice because your skills check will be tomorrow!
