Answer 2

Diana shows the right expression.

Explanation:

We know that 18(24) = 432. So the student that deduct this answer is the correct one.

From the table, we can observe that Diana did the best rewrite process, because it's equal to 18(24), her expression is 18(20+4), which it's a rewrite using distributive property which was ask. Other students didn't use the property correctly.

Therefore, Diana shows the right use of the property, and her expression is equivalent.
