Calling x and y the two sizes of the rectangular field, the problem consists in finding the minimum values of x and y that give an area of

.
The area is the product between the two sizes:

(1)
While the perimeter is twice the sum of the two sizes:

(2)
From (1) we can write

and we can substitute it into (2):

To find the minimum value of the perimeter, we have to calculate its derivative and put it equal to zero:

The derivative of the perimeter is

If we require p'(x)=0, we find


And the other side is

This means that the dimensions that require the minimum amoutn of fencing are (424.26 m, 424.26 m), so it corresponds to a square field.
$20.25 because 8.50 and 8.50 equal 17 and then subtract 2.00 makes 15, and then add 5.25 and you end up with 20.25

D is the answer sorry i dont have a proper explanation
Given sequence: 
.
We need to find first four terms of the sequence.
We already given first term -3.
Let us find second term
.
Plugging n=2.

Now taking n=3.
.
Now, n=4.
.
We got terms -3, 2, 7 and 12.
<h3>Therefore, correct option is B) –3, 2, 7, 12.</h3>
