Alguem pode me ajudar com matemática?Assunto: PG progressão geométrica.?

X² = (x+1)*(x+2) x² = x² + 3x + 2 0 = 3x + 2 3x = -2 x = -2/3 Quando se tem um PG do tipo (a1, a2, a3) , você pode afirmar que que (a2)² = a1 * a3.

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.
