Find the area of a triangle with base 5.8 m and height 9 m.

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.

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

Which expression is not a polynomial?
