You just found out you have to have a cavity filled! UGH! The dentist office informs you that a filling usually costs $150, but that sometimes it can vary but that it will only vary AT MOST $20. What is the range of cost you can expect to pay for your filling? Please help

Factor the monomial completely 42a3b3

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.

Proportions in triangles solve for x
