Answer: The amount of fencing needed can be expressed as 6x + 6 ft and, the cost of fencing can be expressed as Cost = 18x + 18
Step-by-step explanation: The dimensions of the rectangular garden are given as
Length = 2x + 3
Width = x
The amount of fencing that he would need is simply the total measurement all around the rectangular garden, that is, the perimeter. The perimeter of a rectangle is given as follows;
Perimeter = 2(L + W)
With the dimensions already provided we can now substitute for the values
Perimeter = 2(2x + 3 + x)
Perimeter = 2(3x + 3)
Perimeter = 6x + 6
Therefore the amount of fencing needed can be written out as,
6x + 6 ft
If however, fencing costs $3 per foot, then the cost of the entire fencing can be expressed as
Cost = 3(6x + 6)
Cost = 18x + 18
The formula for the volume of a cone is:

We know the radius and the volume, so we can solve for the height.

We start by multiplying both sides by 3.

To finish this problem, we divide both sides by 3.14 to get h on its own.
h = 21.97, so the height of the cone is 21.97 inches.
Yes it is true that a small deviation means the data set tended to cluster around the mean .
27 cubic feet.
You can get this because the surface area formula shows that each edge is 3ft. the area would be length x width x height, which are all 3.
