hero (hero):
I've never seen a question like this before, but I'm going to try to figure it out. That said, I think we can safely eliminate A and C.
hero (hero):
Because x cannot be negative.
OpenStudy (anonymous):

hero (hero):
What country are you from? That will help.

Or rather...do you have the ability to change your answer later? I'm still checking.
OpenStudy (anonymous):
nope
hero (hero):
RQ < OR
2x + 3 < 9
2x < 6
x < 6/2
x < 3
OpenStudy (anonymous):
A.B.C are options o: ok
OpenStudy (anonymous):

lol, I'm pretty sure B is correct. The only reason I didn't pick it is because I thought you already picked it.
OpenStudy (anonymous):
xD sorry! thanks for spending so much time on this problem. :|
OpenStudy (anonymous):
heh !
hero (hero):
Actually, C is correct. I will explain
hero (hero):
The length RQ has to be greater than zero so
2x + 3 > 0

and x > -3/2 after solving
hero (hero):
Also we know 2x + 3 < 9
hero (hero):
solving that gets you x < 3
hero (hero):
So -3/2 < x < 3
is correct. Option C
