Best ResponseYou've already chosen the best response.0and the third question is: using f+v=e+2 find the unknown number 1) faces:? vertices: 6 edges: 12 2) faces 5, vertices ?, edges 8 3) faces 7, vertices 10, edges ?

Best ResponseYou've already chosen the best response.0faces:? vertices: 6 edges: 12 f + 6 = 12 + 2 2) faces 5, vertices ?, edges 8 5 + v = 8 + 2 3) faces 7, vertices 10, edges ? 7 + 10 = e + 2

Best ResponseYou've already chosen the best response.0It might be a trapezoid, I can't see it too well, and yes those equations are correct, now solve! :)
