100 pts for truly honest ansewr correctly identify the property shown. (−5.2+(−8.4))+(−2.8)=−(5.2+8.4)+(−2 .8)

Distributive property because if you divide -5.2+(-8.4) by -1, you get -(5.2+8.4)

When you cancel everything out it will be. -(5.2 + 8.4)

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

The first one is correct
