Is x > 5 ?
1. x^2 > 25
2. 2x + 7 > 0
Is the answer C ?
Here is how i worked it out
1. x > 5 or x < -5
so, insufficient
2. 2x > -7
=> x > -3.5
so, insufficient
Combining the two x > 5. Hence, C.

In statment two we know that X is greater than - 3.5
Statment one tells is X = 5 or X = -5
When we combine we know that x is 5
So it answer the questions if X > 5 and the answer is NO it is not greater than 5 it is 5
