A student says that his father showed him a very simple method for dealing with expressions like - (a-b+1) and x-(2x-3). The rule is, if there is a negative sign before the parentheses, change the signs of the expressions inside the parentheses. Thus, (a-b+1)= -a+b-1 and x-(2x-3)=x-2x+3. What is your response? Which response is correct? ... OA. By the definition of the associative property of multiplication this statement is incorrect. Therefore, the father is incorrect. O B. By the definition of the distributive property of multiplication over addition and subtraction this statement is incorrect. Therefore, the father is incorrect. OC. By the definition of the distributive property of multiplication over addition and subtraction this statement is incorrect. Therefore, the father is correct. OD. Since for all integers c, -c=(-1)c, the effect of performing the opposite of an algebraic expression is the same as multiplying the expression by - 1. Therefore, the father is correct.
