Answer:
Your answer is 7
Hope this helps!
Step-by-step explanation:
You plug 14 in for x then just do 14-7 and you will get 7
 
        
                    
             
        
        
        
Okay, so first you draw a picture and let x be the distance from point D to the rest stop. Then the distance from point  to the rest stop is  8 - x
You know that the length of the new trail is y + z, where y is the distance from Ancaster to the rest stop and z is the distance from Dundas to the rest stop. 
Now by the Pythagorean theorem,  y^2 = 4^2 + x^2 and  z^2 = 6^2 + (8 - x) ^2
So take square roots of these, add them, and minimize. 
Note: I am assuming the path is perfectly straight, otherwise this approach fails.
        
             
        
        
        
A : y is greater than or equal to 4x plus two
        
             
        
        
        
We want to solve
y'' + 3y' = 0
Solve the indicial equation.
m² + 3m = 0
m(m + 3) = 0
m = 0 or m = -3
The basic solutions are e⁰=1 and 

.
