Anises hair has to be greater than her sisters Hair>2.25
Answer:
The -1 came from factoring.
The equation is multiplied by 8 because 8 could be pulled from 16x-8.
16 can be divided by 8 2 times and 8 can only divided by 8 once.
so factoring it makes the equation 8(2x-1)
If there are no restrictions, there can be;
6 ways x 6 ways x 6 ways x 6 ways x 6 ways x 6 ways = 6^6 ways for the letters a, b, c, d, e and f to be arranged.
However, if you want to arrange them so that each letter is used only once;
6 ways x 5 ways x 4 ways x 3 ways x 2 ways x 1 way = 6! ways
