B. p > 3
C. p > -21
D. p > -3

#2 what is 9-12?

Answer 2

1. is good , 2. is not

inequalities solve just like equations (equalities)
... the only big difference is that multiplying or dividing by a
... negative quantity changes the direction of the "arrowhead"

2. you have to subtract 12 to get p by itself ... p > 9 - 12

9 - 12 is -3, so it's D?
