The area of a rectangle is modeled by the polynomial (8x^3-6x^2-5x+3) square units. The width of the rectangle is modeled by the polynomial (x+3/4) units. Showing all work, write a polynomial that represents the length of the rectangle.

The temperature of a chemical solution is originally 21 ? c . a chemist heats the solution at a constant rate, and the temperature of the solution 75 ? c after 1212 12 minutes of heating. the temperature, tt t , of the solution in ? c is a function of x , the heating time in minutes. write the function's formula.
