The growth of a rectangle that started with a width of 5 inches and a length of 8 inches. At time zero the width started growing at a constant rate of 2 inches per minute, and the length began growing by 3 inches per minute. We found that the equation for the area A (in square inches) as a function of time t (in minutes) was A = 6t 2 + 31t + 40. Determine the average rate of increase in area with respect to time from time 5 minutes to time 15 minutes Please help, my assignment is due in an hour
