Answer:
D
Step-by-step explanation:
The area of a rectangle is given by the formula:

So, we are given that the area is:

And the width is:

And we want to find the length. To do so, first substitute the expressions into the equation:

Thus, to find the length, divide by (x²+3):

So, factor the numerator:

From the first two terms, factor out a x^2.
From the third and fourth terms, factor out a 3:

Combine:

Putting this back:

Cancel:

And that's our answer :)
I believe it would be D.
A
since it doesn’t pass the vertical line test, which proves if a graph is a function.
Answer: 173.3 feet
Step-by-step explanation:
The answer is A because you need to find the unit rate of each cost
Since $2.80 is for 2 liters, do 2.80/2 which equals 1.4. So that’s the cost for one liter
Then, 6 half liter bottles is just 3 liters because 6*1/2= 3. Then to find the unit rate for that, do 3.90/3 which equals 1.3.
So the first option is $1.40 per liter and the second option is $1.30 per liter so the first option is more expensive- the 2-liter bottle, and the cost for that is 1.40
Hope this helps:))
