What is the area enclosed by the curves f ( x ) = x 3 − 8 x 2 + 18 x − 5 f(x)=x 3 −8x 2 +18x−5 and g ( x ) = x + 5 g(x)=x+5 ?

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.
