Answer:
The correct answer is D
Step-by-step explanation:
My reason for giving this answer is because this problem is written in expression form. Since there is a variable in the expression, You cannot solve X-7 without outside information on the value of X. So D would be the answer because The answer to a multiplication problem is called the product, Then the answer to a subtraction problem is a difference. Answer D says "The product of a number and a difference", Which would mean multiplication and subtraction.
