Open the brackets.. You get -11 -6 + 9r It is C. right !

OpenStudy (anonymous):

It would be C, Just remove the parenthesis, do negative eleven minus 6, giving you negative seventeen. The negative in the parenthesis in -9r is positive since 6 is removed from the parenthesis. Your answer is C: -17+9r.
