Answer: Required equation :
Dimensions of the pen:
Width = 12 feet and Length =36 feet.
Step-by-step explanation:
Let w be the width of rectangular pen, then the length of the rectangular pen will be 3w.
We know that the perimeter of rectangle is given by "2length+2width".
Perimeter of rectangular pen = 2(3w)+2(w) =6w+2w=8w (1)
Given : You have 96 feet of fencing to enclose a rectangular pen for your dog.
i.e. Perimeter of rectangular pen = 96 feet (2)
From (1) and (2), we get
[Divide both sides by 8]
Thus, width = 12 feet and length = 3(12)=36 feet.

Answer:
Yes Kevin is correct
Step-by-step explanation:
The index, x, of a radical ˣ√ is the numerical value of the root sought of the number located under (within) the radical sign
Therefore, when the index is even, we have, numbers for the radical given by 2x, therefore we have;
⁽²ˣ⁾√(a²ˣ)
Where a = The 2x root of the radicand
Therefore, we can write, a²ˣ = aˣ × aˣ
For which aˣ can be neqative but will still give a positive value
Therefore, when the index is even, the roots can either be a positive or a negative real number, which are two real numbers, +a or -a
If the integral is
substitute and
. Then you end up with
which in terms of <em>x</em> is
