Answer:
For any two given points (x1,y1) and (x2,y2), the slope = (y2-y1)/(x2-x1)
Let's take the points (15,3) and (30, 6):
slope = (y2-y1)/(x2-x1)
= (6-3)/(30-15)
=3/15
=1/5 =0.2
The slope, in general, means the rate of change of y, relative to x. In the context of this question, the slope tells us that the amount of concrete that can be poured (in yards) is a fifth of the time taken (in minutes).

f (x).g (x)=(-4x-2).2x
f (x).g (x)=-4x.2x-2.2x
f (x).g (x)= -8x^2-4x
The rectangle's area is the product of its length and width. Differentiating both the area and the product with respect to time 
gives
The length and width increase at respective rates of 
and 
.
At the moment
