9. Identify the correct property being shown. (-5.2 + (-8.4)) + (-2.8) = -(5.2 + 8.4) + (-2.8)

-16.4, (commutative property)

Step-by-step explanation:

(add, because they are both negatives) -5.2+(-8.4)= -13.6

Then add the (-2.8): -13.6 + (-2.8) = -16.4

Thats your first equation!!!

do the same thing for the other one, and by the way it the same answer.

Its commutative prop because its just switching positions and its adding negatives.

i think asking google will you get the answer to that question
