15 points! a company distributes its product by train and by truck. the cost of distributing by train can be modeled as −0.06x^2 + 32x − 100, and the cost of distributing by truck can be modeled as −0.04x^2 + 26x − 170, where x is the number of tons of product distributed. write a polynomial that represents the difference between the cost of distributing by train and the cost of distributing by truck. a −0.1x^2 + 6x − 270 b −0.02x^2 + 58x − 270 c −0.02x^2 + 6x + 70 d −0.02x^2 + 6x − 270
