Yes because you have to divide p to solve for n
OpenStudy (anonymous):
it is divided by p in all of them
OpenStudy (anonymous):
It is A pay attention @zaibali.qasmi and look at the problem carefully
OpenStudy (anonymous):

You also have to FOIL and you get 3c - 15
OpenStudy (anonymous):
That is why it is A
OpenStudy (anonymous):
oh now i get it thank you guys so much :)
OpenStudy (anonymous):
-np-6=< 3c-15
-np-6+6=< 3c-15+6
-np=<3c-9
n>= (3c-9)/p
coz you hhave to mulitiply it with -1 along with whiich chnages the mid innequality sign
OpenStudy (anonymous):
okay now i am really confused
