With this question, the distributive property means to distribute each term in the left parentheses to each term in the right parentheses.
= (-5 - c)( -1)
multiply each term in left parentheses by each term in right parentheses
= (-5 * -1) + (-c * -1)
multiply in parentheses; negative times negative equals positive
= 5 + c
ANSWER: 5 + c
