Your proportion should look something like this
After cross multiplication, you should end up with this equation
After dividing 4 on both sides, you should get that x=9
Step-by-step explanation:
2-5^3+6x
2-125+6x
6x+2-125
6x-123
Part A
The four plastic sides comprises of two equal squares of area
each and two equal rectangles of area
each.
Given that t<span>he total area of the four plastic sides is to be
, thus:
The volume of the figure is given by: Volume = Area of base x depth
Part B:
For maximum volume, the derivative of V with respect to x will equal 0.
But dimensions has to be positive, thus the value of x which produces maximum volume is x = 14.14
Recall that
Therefore, the </span><span>dimensions that will maximize the volume of the shelter is x = 14.14 and y = 28.29</span>
