What is the prime factorization of 27720?

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.

Polynomial that can be factored as (3x-4)(3x+4)

If 5x - 2 = -12, then x = a) -50 b) -4.4 c) -2.8 d) -2
