The graph below shows the solution set of which inequality?

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

13664

step-by-step explanation:

=cross multiply

=100 x = 13664

so the rectangle is 80cm (area)

now to find the area of a triangle.

base times height.

4 times 8.

your answer is 96cm.

hope this .
