I agree it should be C.Kumar007 wrote:What is the value of |x+7|?
1. |x+3| = 14
2. (x+2)^2 = 169
Well the ans is D.
But can anyone please explain what is wrong with C
1. x could be either 11 or -17 INSUFFICIENT
2. x could be either 11 or -15 INSUFFICIENT
Combine both together so that x = 11 and you have your answer.
Must be C.
