Question

Determine which of the following situations requires the distributive property in order to simplify the expression. Select all situations that apply.

x(2y)
9(x ∙ y)
9(x + y)
(7 ∙ a)(b)
(7 - a)(b)
(2 ∙ x) ∙ y

*(OML PLEASE HELP ME ON THIS IT'S DRIVING ME NUTS!)*

Answer 1

9(x + y)
(7 - a )(b)

9(x ∙ y), the distributive property is not used because (x ∙ y) = xy which means that only one term can be multiplied by the term outside the parenthesis.

(7 ∙ a)(b), the distributive property is not used because (7 ∙ a) = 7a which means that only one term can be multiplied by the term outside the parenthesis.
