Which is an example of the opposite of a sum property?
A.
–17 + 32 = 32 + (–17)
B.
–26 + (4 + 8) = (–26 + 4) + 8
C.
–5(6 + 3) = –5(6) + –5(3)
D.
–(–17 + 5) = 17 + (–5)

think of it like this
start by doing a sum. Basically add 2 numbers up
when you take the opposite of that sum, you are making the result a different sign. So if the sum is negative, it turns positive, or vice versa

so is it c

C would be distributive property
a*(b+c) = a*b + a*c

so i am right @jim_thompson5910
jimthompson5910 (jim_thompson5910):
the `opposite of a sum property` and the `distributive property` are two different properties
OpenStudy (anonymous):
ok it is d
jimthompson5910 (jim_thompson5910):
yeah since -17+5 is the sum
-(-17+5) is the opposite of the sum
