Step-by-step explanation:
Equations:
Quantity:: d = n + 3
Value::: 10n + 5d = 615 cents
-------------------------------------------
Modify::
d - n = 3
d + 2n = 123
--------------------------------------------
Subtract and solve for "n"::
3n = 120
n = 40 (# of nickels)
d = n+3 = 43 (# of dimes)
A Polygon is a two dimensional figure that can be drawn on a flat surface.A cube is a three dimensional figure that can be sculpted in three dimensions but can only have projections of it drawn on a flat surface.So a cube is not a polygon.
