Explain how to determine if the two expressions are equivalent using x = 6 and x = 2.

2x + 4 – 1 3 + x + x

Two parallel lines are crossed by a transversal.what is value of x

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)
