Well your numerator can be factored to (x-5)(x+5), so the (x-5) in the denominator will cancel out with it leaving just (x+5), so 5+5=10. Hope that helps.
It is x+5. Unless you mean x+5=5, then it would be x=0.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
