Answer:
D)4x + 6/(x + 1)(x - 1)
Step-by-step explanation:
A field is basically a rectangle, so to find the perimeter of our field we are using the formula for the perimeter of a rectangle
![p=2(l+w)](https://tex.z-dn.net/?f=p%3D2%28l%2Bw%29)
where
is the perimeter
is the length
is the width
We know from our problem that the field has length 2/x + 1 and width 5/x^2 -1, so
and
.
Replacing values:
![p=2(l+w)](https://tex.z-dn.net/?f=p%3D2%28l%2Bw%29)
![p=2(\frac{2}{x+1} +\frac{5}{x^2-1})](https://tex.z-dn.net/?f=p%3D2%28%5Cfrac%7B2%7D%7Bx%2B1%7D%20%2B%5Cfrac%7B5%7D%7Bx%5E2-1%7D%29)
Notice that the denominator of the second fraction is a difference of squares, so we can factor it using the formula
where
is the first term and
is the second term. We can infer that
and
. So,
. Replacing that:
![p=2(\frac{2}{x+1} +\frac{5}{x^2-1})](https://tex.z-dn.net/?f=p%3D2%28%5Cfrac%7B2%7D%7Bx%2B1%7D%20%2B%5Cfrac%7B5%7D%7Bx%5E2-1%7D%29)
![p=2(\frac{2}{x+1} +\frac{5}{(x+1)(x-1})](https://tex.z-dn.net/?f=p%3D2%28%5Cfrac%7B2%7D%7Bx%2B1%7D%20%2B%5Cfrac%7B5%7D%7B%28x%2B1%29%28x-1%7D%29)
We can see that the common denominator of our fractions is
. Now we can simplify our fraction using the common denominator:
![p=2(\frac{2(x-1)+5}{(x+1)(x-1)} )](https://tex.z-dn.net/?f=p%3D2%28%5Cfrac%7B2%28x-1%29%2B5%7D%7B%28x%2B1%29%28x-1%29%7D%20%29)
![p=2(\frac{2x-2+5}{(x+1)(x-1)} )](https://tex.z-dn.net/?f=p%3D2%28%5Cfrac%7B2x-2%2B5%7D%7B%28x%2B1%29%28x-1%29%7D%20%29)
![p=2(\frac{2x+3}{(x+1)(x-1)} )](https://tex.z-dn.net/?f=p%3D2%28%5Cfrac%7B2x%2B3%7D%7B%28x%2B1%29%28x-1%29%7D%20%29)
![p=\frac{4x+6}{(x+1)(x-1)}](https://tex.z-dn.net/?f=p%3D%5Cfrac%7B4x%2B6%7D%7B%28x%2B1%29%28x-1%29%7D%20)
We can conclude that the perimeter of the field is D)4x + 6/(x + 1)(x - 1).

are 30/12 and 40/16 equivilent?
if a/b=c/d then a/b times d/c=1
basically if ad=bc then they are equivilent
30/12 ad 40/16 equvilient?
30/12 times 16/40=1?
480/480=1?
1=1?
yes
they are equivilent
13 percent * 5 years = 65
65% of the cheetah population will be lost in 5 years.
100 percent - 65 percent = 35.
35% of the cheetah population will remain in 5 years.
I do not see how this is a high school question, it's easy.

What is 15.41 rounded to the nearest hundredth?
Rounding to the Nearest Hundredth. Rounding decimals is very similar to rounding other numbers. If the thousandths place of a decimal is four or less, it is dropped and the hundredths place does not change. For example, rounding 0.843 to the nearest hundredth would give 0.84.
