Answer:
Therefore values of a and b are

Step-by-step explanation:
Rewrite  in the form
 in the form 
 
 
where a and b are integers, 
To Find:
a = ?
b = ?
Solution:
 ..............Given
 ..............Given
Which can be written as
 
 

Adding half coefficient of X square on both the side we get
 ...................( 1 )
 ...................( 1 )
By identity we have (A - B)² =A² - 2AB + B²
Therefore,

Substituting in equation 1 we get

Which is in the form of

On comparing we get
a = 3 and b = 2
Therefore values of a and b are

 
        
             
        
        
        
It is given that, ABC BC =6.5cm CA=6.3cm AB=4.8cm Steps involved in construction Step 1: First draw a line segment AB = 4.8cm using pencil and ruler And mark one end A and other end B Step 2: From the point A draw an cm Step 3: From the point B draw an arc of length 6.5 cm Step point of intersection of these arc as C. Step 5: Join A and C & B and C. Now the triangle ABC is ready with BC =6.5cm CA=6.3cm AB=4.8cm
 
        
             
        
        
        
Now, if x = 300 miles, then 
 y= 1/20*300 + 35 
 y = 15 + 35 
 y = 50, therefore it would cost $50.00 to drive the rental car 300 miles.
