You can clear the zeros in the equation from the exponents. after you factor it should be
Sum of two sides of the triangle should be more than 3d side.
n<20+5,
n<25
Third side should be more than difference of two other sides.
n> 20-15
n>5
So, n should be
5<n<25.
The ratio of Blue to red in the purple shade that Patrick wants is:
