If the manager wants to use more Big Red trucks than Common Joe’s trucks, plot a graph that shows the number of trucks used, given all 3 constraints. Replace the inequality sign with the equal sign. Use the Graph tool to graph all three equations and paste the resulting graph into the box below. Describe which part of the graph should be shaded and whether the lines should be dashed or not.

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .

the anwser is x< -17/2
