Using proportions, it is found that the estimate of the the per capita consumption from 2011 was of 29.25 gallons.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The amount in 2012 was a increase of 5.3% from 2011, that is, 105.3% = 1.053 of x, and the consumption per capita was of 30.8 gallons, hence:
1.053x = 30.8
x = 30.8/1.053
x = 29.25 gallons.

I'm going with 10. Let me know.
(x+2)^2
This can be rewritten as:
(x + 2)(x + 2)
Multiply everything in the second parenthesis by x.
x^2 + 2x
Multiply everything in the second parenthesis by 2.
2x + 4
Add these equations together.
x^2 + 2x + 2x + 4
Combine like terms.
x^2 + 4x + 4
Hope this helps!
Answer:
C. 
Step-by-step explanation:
Using this formula will help you determine which <em>rate of change</em> [<em>slope</em>] is the greatest:
This tells you that when −x is multiplied by −4, you get 4, and since 2 is less than 4, you have your answer.
