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?
How many diagonals are in the fifth polygon of this sequence of regular polygons below?
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
this has already been solved by melody and solution completed by arnolde
