[pinnacle]

if |a+4|=2 what is the value of a

1. a<0
2. a^2 +8a + 12=0

[shibal]

IMO E

from the stem we get that a can be -2 or -6

stmt 1 says a<0 so, could be -2 and -6 insuff

stmt 2 if we foil the equation will get (a+6)(a+2) which is also -2 and -6.... insuff

combining both we don't get that far..... so E

oa?

[mehravikas]

IMO - E

[Naruto]

IMO E

A alone is insufficient as a could be -6 or -2

B alone is insufficient as the equation again gives the same condition as A

both combined dont give a unique solution.

OA?
