How many different ways can you make 12 cents in change?
I'll use these symbols for each coin: P = Penny; D = Dime; N = Nickel 12 P 7 P & 1 N (7 + 5) 2 P & 2 N (2 + 10) 1 D & 2 P (10 + 2)
Is a circle concave or convex?
This depends on your definition. One could say that circles ({p in R^n : d(p,m) = r}) are concave, while (open) disks ({p in R^n : d(p,m) < r}) are convex.

What is the formula for the width of a rectangle?
The area ,A, of a rectangle is the length, L, multiplied by the width, W. A=LW hence W=A/L. The perimeter, P, of a rectangle is P= 2(L+W) or 2L+2W. 2W=P-2L and W=(P/2)-L. The Square of the diagonal of a rectangle, D^2 =W^2+L^2 so that W^2=D^2-L^2 and W=sqrt((D^2-L^2). You could also express the width using trigonometric functions, but this is probably enough to get you started.
