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 me on this it's driving me nuts! )*

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. 

inch

step-by-step explanation:

yard and mile are too big.

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
