Answer:
1).
2).
Step-by-step explanation:
Here the given equation is 
We have to factor the perfect square trinomial on the left side of the equation
So left side of the equation is 
= 
since [(a+b)²= a²+b²+2ab]
Therefore the factorial form of the equation will be

Now we have to solve the equation by applying square root property


The population density is approximately 4 people per square mile
<h3>Calculating Population Density </h3>
From the question, we are to determine the population density
Population density is given by the formula,

Number of people in the town = 12620 people
Now, we will determine the land area of the town
From the given shape,
Land area of the town = (60 × 65) - (25 ×40)
Land area of the town = 3900 - 1000
Land area of the town = 2900 square mile
∴ Population density = 
Population density = 4.3517
Population density ≅ 4 people per square mile
Hence, the population density is approximately 4 people per square mile

Answer:
$213.095
Step-by-step explanation:
15% of 185.30 = 185.30/100*15 = 27.795
So to find what is 15% added to 185.50, we use 185.30 + 27.795 = $213.095

Answer:
the ratio of horizontal change compared to vertical change
Step-by-step explanations
slope = difference of y/ difference of x
rise (y) over (/) run (x)
change in y over change in x (y/x)
horizontal change (x): to vertical change (y) WRONG
61/66=0.9242 So in % that is %92.42
