Answer:
34.5 ft
Step-by-step explanation:
~Refer to the attachment for the solution.
 
        
             
        
        
        
45 / 2 = 22.5 
You can get 22.5 hours of Internet for 45$.
        
                    
             
        
        
        
To do these, start by looking at the "b" value -6. 
divide it by 2 
-6/2 = -3
now square this number
(-3)^2 = 9
this is what you need for the "c" value
there is only a 5 for the c value so add 4 to both sides of the equation. ( +4 = +4) 
y +4 = x^2 -6x +5 +4 
y +4 = x^2 -6x +9 
y +4 = (x -3)^2 
y = (x -3)^2 - 4
vertex ( 3, -4) upwards facing like a bowl, because the "a" value is positive. So the vertex is the minimum, lowest point on the graph. 
        
             
        
        
        
Option C: (x+4) and (x-1) are the factors of the equation 
Explanation:
Given that the equation is 
We need to determine the factors of the equation.
Splitting the middle term, we get,

Grouping the terms, we have,

Let us factor out the term (x+4), we have,

Thus, the factors of the equation are (x+4) and (x-1)
Hence, Option C is the correct answer.
