Answer:
y = 16x + 6 
Step-by-step explanation:
They charge $14 for each DVD, which mean the slope of the function is 14
You must pay an additional $6 for shipping and handling, which means no matter how many DVD you buy, you have to pay a flat fee for $6  
So our function is: 
y = 16x + 6 where: 
y is total cost
x is the number of DVD you buy (x>0) 
 
        
             
        
        
        
It's growth and the y-intercept is (0,2). ;)
        
             
        
        
        
G=38
Whenever you divide or multiply by one the number stays the same, therefore just take out all the xs and then solve the equation. I hope this helps!
        
             
        
        
        
Answer:
10
Step-by-step explanation:
A= L²
50 = L² (do opposite operation to find L)
L = 7.07
x²= L²+ L²
x²= 7.07² + 7.07²
x² = 100 ( do opposite operation to make x the subject)
x = 10
Note: opposite operation of square is square root
