Answer:C. 7 * (2 * 2)

Step-by-step explanation:Figure out the original expression to see the equivalent expression.

(7 * 2) * 2

14 * 2

28We have to look for an expression that equals 28.

A is (7 + 2) * 2.

(7 + 2) * 2

9 * 2

18A equals 18, so it’s not equivalent to the original expression.

Now B, which is (2 * 2) + 7

(2 * 2) + 7

4 + 7

11B equals 11, so it is also not equivalent.

Now C; that is 7 * (2 * 2)

7 * 4

28C equals 28, so that is equivalent. Although we have found our answer, we need to make sure it’s right by evaluating D. ((2 * 7) + (2 * 2))

(2 * 7) + (2 * 2)

14 + 4

18D, like A, equals 18, so it is also incorrect.

C is the only expression that is equivalent to (7 * 2) * 2, so it is the answer.
