Progressão Aritmética e Progressão Geométrica?

(a - r) + a + (a + r) = 36 3a = 36 a = 12. Se alguém tem um triângulo real, ele satisfaz a desigualdade triangular a - r <= a + a + r (óbvio) a <= a - r + a + r (óbvio) a + r <= a + a - r 2r = r/2 Nós não somos obrigados a ter 8, 12, 16. Por exemplo, 9, 12, 15 ou 7, 12, 17, estão correctas.

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.
