Suppose you have 4 colors to color the 3 edges of an equilateral triangle. how manyways can you color the triangle if two ways are considered the same if they differby a rotation? include a clear description of how you came to your number.

4

Step-by-step explanation:

There will be the number of ways to arrange n objects. In fact, the factorial method is used to calculate the number of ways for arranging n objects will be like this:

n! = n * (n-1)* (n-2)* (n-3) * ...*3*2*1

Another method will be to sue the binomial method or combinations:

(n r) =

To arrange 4 colors over 3 edges, this means that:

n =

  = 4

Therefore, there will be 4 ways of arranging the numbers.  

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
