Instructions

(1.4.1) Evaluate each of the following first by computing the expression inside the parentheses, then by using the distributive property to expand the product.  
For example,  
2 x (8 - 3) = 2 x 5 = 10
2 x (8 - 3) = 2 x 8 - 2 x 3 = 16 - 6 =10

Untitled Section

6 x (3 + 5)

(4 +8) x (-2)

7 x (5 - 2)

(8 - 13) x (-3)

(1.4.2) Richard expanded the product (-2) x (5 - 3) like this
(-2) x (5 - 3)=
(-2) x 5 + (-2) x (3) =
-10 + (-6) =
-16

(1.4.3) Factor a 4 out of each expression in the parts below. For example, 36 + 44 = 4 x (9 + 11).
