can someone help with what 3(2x-7)+8(4-x)?

OpenStudy (anonymous):

distribute : 6x-21+32-8x combine like terms : -2x+11

OpenStudy (anonymous):

you sure because when multiplying 3*-7 it equals 6x- -21 same with -8x

OpenStudy (astrophysics):

\[3(2x-7)+8(4-x)=6x-21+32-8x \implies -2x-11\]

OpenStudy (astrophysics):

Yes, @speedygonzales is correct.
