Answer:
6x² + 15
6
Step-by-step explanation:
Let the number be x.
"the square of a number"
x²
"the product of 6 and the square of a number"
6x²
"the product of 6 and the square of a number plus 15"
6x² + 15
The coefficient is the number that multiplies the variable, so it is 6.
 
        
             
        
        
        
35+35+35+35+35+35+35+35+35+35+35+35
Or 
35×12
=420
        
             
        
        
        
FV =  PV / (1 +r)^n
Where FV = Future Value,  PV = Present Value, r = inflation rate in %,
n = number of years.
PV = $38, r = 4%, n = 3 years.
FV =    38 / (1 + 4%)^3
      =   38 / (1 + 0.04)^3
      =     38 / (1.04)^3 =    33.782
Hence the value 3 years from now = $33.78     
        
             
        
        
        
Volume = PI x r^2 x H/3
3.14 x 8^2 x 13.5/3
3.14 x 64 x 4.5 = 904.32 cubic feet
        
             
        
        
        
The distance is 6 I think
