Use the Distributive Property to rewrite each product below. Simplify your answer.

  • Write the above product as and make a generic rectangle like the one at right. Generic rectangle: Top edge labeled: 20 on left, and + 8 on right. Left edge labeled: 60 on top, and + 3 on bottom. Interior sections are blank.

  • Find the product for each part of the rectangle. Added to the Generic rectangle: Interior sections labeled as follows: top left: 20 times 6 = 1200; top right: 8 times 6 = 480. bottom left: 20 times 3 = 60. bottom right: 8 times 3 = 24.

  • Sum the products:

 

  1. Write this product as and create a generic rectangle similar to the one for part (a).
