Which is true about the degree of the sum and difference of the polynomials 3 x to the 5th power y minus 2 x cubed y to the 4th power minus 7 x y cubed and negative 8 x to the 5th power y plus 2 x cubed y to the 4th power plus x y cubed ?
Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures cell phones can be modeled by the polynomial 2x2+55x+10. The cost, in dollars, of producing the cell phones can be modeled by 2x2−15x−40. The variable x represents the number of cell phones sold. What expression represents the profit, and what is the profit if 240 cell phones are sold?
