1) a could be also negative
2) x+y>0 we do know that is positive but this is not guaranteed. We do not the sign of x and y
3) dividing both side by a^2 what is left is \(x \geq y\) and is given that x>y
This is the only true option
2) x+y>0 we do know that is positive but this is not guaranteed. We do not the sign of x and y
3) dividing both side by a^2 what is left is \(x \geq y\) and is given that x>y
This is the only true option

For 3) after dividing by a^2, we get x >= y. This implies that x could be = y which is in violation of the given constraint. Therefore, none of the given options is correct.
