Some one me ! i really need it me out extra points !

The total cost of anja’s trip to the dentist was $628.35. she paid a flat fee of $89.95 which included the checkup and cleaning and then had 4 cavities filled, each of which cost the same amount. which shows the correct equation and value of x, the cost of each cavity filling?

If y varies directly as x2 and y=6 when x=6, find the constant of variation.

Factor the expression using gcf 9b+45
