The sum of two polynomials is 8d5 - 3c3d2 + 5c2d3 - 4cd4 + 9. If one addend is 2d5 - c3d2 + 8cd4 + 1, what is the other addend?

Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures televisions can be modeled by the polynomial 3x2 + 180x. The cost, in dollars, of producing the televisions can be modeled by 3x2 - 160x + 300. The variable x is the number of televisions sold. If 150 televisions are sold, what is the profit?

The revenue, in dollars, of a company that makes toy cars can be modeled by the polynomial 3x2 + 4x - 60. The cost, in dollars, of producing the toy cars can be modeled by 3x2 - x + 200. The number of toy cars sold is represented by x. If the profit is the difference between the revenue and the cost, what expression represents the profit?
