<h3>
Answer: C) 5</h3>
==========================================================
Work Shown:
s = square side length
A = area of square = 9x^2+12x+4
A = s^2
A = (ax+b)^2
A = a^2*x^2 + 2abx + b^2 .... apply the FOIL rule
A = 9x^2 + 12x + 4
Equating corresponding terms, we see that,
- a^2*x^2 = 9x^2 which shows that a^2 = 9 and that solves to a = 3, assuming 'a' is positive.
- 2abx = 12x leads to 2ab = 12 or ab = 6. Using a = 3 we can find that b = 2.
- b^2 = 4 solves to b = 2 which matches with the previous value of b found.
Using a = 3 and b = 2, the sum of the values is a+b = 3+2 = 5, so that's why the answer is choice C.
Side note: 9x^2 + 12x + 4 factors to (3x + 2)^2
Answer:
Andy went as furthest as possible with a gallon of gasoline
Step-by-step explanation:
Let
m ----> the distance in miles
g ----> the number of gallons of gas
step 1
<u><em>Kelley's Mileage</em></u>
Find the slope of the linear function of Kelley's Mileage
we have the points
(0,0) and (20,50)
the linear equation is
step 2
<u><em>Andy's Mileage</em></u>
Find the slope of the linear function of Andy's Mileage
we have the points
(15,78.75) and (30,157.5)
the linear equation is
step 3
Rick's Mileage
we have
therefore
the slope is 
step 4
Compare the slopes
therefore
Andy went as furthest as possible with a gallon of gasoline

Answer:
If you mean a part to part ratio, this basically describes a ratio or relationship that compares two different groups.
Step-by-step explanation:
If you mean a part to part ratio, this basically describes a ratio or relationship that compares two different groups.
An example would be if I compared the number of dogs to cats in a house. If there were 10 dogs and 3 cats, I would write 10:3.
Hope this helped! God bless and stay safe :)
