X=700R+85Y
R= Number of Refrigerators
Y= Number of Years
The first one is 2.78% second one is 3.8% third one is 4.5% and it will be 378
Polygon Diagonals. The number of diagonals in a polygon = n(n-3)/2, where n is the number of polygon sides. For a convex n-sided polygon, there are n vertices, and from each vertex you can draw n-3 diagonals, so the total number of diagonals that can be drawn is n(n-3).
