+33 My school's math club has boys and girls. I need to select a team to send to the state math competition. We want people on the team. In how many ways can I select the team without restrictions?
+33 How many diagonals are in the fifth polygon of this sequence of regular polygons below?
+163 Unfortunately Guest's solution is wrong
The answer is 14 diagonals in a heptagon
why?
the formula for determining the number of diagonals on a polygon is n(n - 3)/2
7*4/2 = 14
