Answer:
The answer is 3
Step-by-step explanation:
36÷12=3, which is the lowest number on either side of the boxes
Take first derivative of area function and set it to zero
da/dx=24 - 2x=0
Now it is set to zero add -2x to both side
24 - 2x = 0
24 = 2x
Now divide by 2 in both sides
12 = Width
Your width now is 12
Plug 12 into you equation like this:
24 (12) - 12^2= A
288 - 144 = A
144 = Area
144 feets is the maximum area using the width 24
Answer:
The correct option is B.
Step-by-step explanation:
The given vertices are (-4,2),(1,2),(1,-3) and (-4,-3).
Plot these point on a coordinate plate. From the graph it is noticed that the given quadrilateral is a square.
Distance formula:

Use distance formula to find the side length.


Since both consecutive sides are equal therefore it is a square.
Area of a square is

Where, a is side length.
The side length of the square is 5. So, area of ABCD is


Therefore the area of quadrilateral is 25 units square. Option B is correct.
A. If you draw the graphs you will find that B, C and D are all false.
The answer is definitely 6
