Answer 1

(9) • (-3+8)

We know that (-3 + 8) • (9) is equal to the expression above because of commutative property.

If we apply the -1 on "-(3-8) • (9)" we get (-3+8)x(9) which looks exactly like the first answer choice.

Assuming that I'm reading the third answer correctly, it is not equivalent because the 9 has to be applied to the -3 and the 8 for distributive property to work.

The last answer choice is an example of distributive property and is equivalent.
