Answer is b

m= -6

I am getting E as well.

From the question we know: m=-2 or m=-6

From Statement 1: It can be anything
From Statement 2: m = -2 or m =-6

Taken both together...insufficient

Isn't the answer the common as highlighted above? i.e. m = -6.
Hence B.

Yeah, this is E. We can't eliminate m = -2 or m = -6. they are both valid.

the answer is e
the modulus equation can have two solutions: -6, -2.
st 1 is insufficient, since it is appropriate for both solutions.
st 2 is also insufficient, since its solutions are also -6,-2

Ans is E

1) M<O= It can be anything less than 0

2) After calculation we get m=-6 or -2

so E is the answer.

St1: m < 0, so m = -6 or m = -2. Insufficient.

St2: m^2+8m+12=0 --> (m+2)(m+6) = 0
m = -2, m = -6. Insufficient.

Using St1 and St2:
Does not help us narrow to one value of m. Insufficient.

Ans E
