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)

OpenStudy (anonymous):

jimthompson5910 (jim_thompson5910):

this is similar to the last problem you had me look at

jimthompson5910 (jim_thompson5910):

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

OpenStudy (anonymous):

so is it c

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

ok have more please i am hard to work with
