Answer:
(w^2 - 4w + 16)
Step-by-step explanation:
Note that w^3 +64 is the sum of two perfect cubes, which are (w)^3 and (4)^3.  The corresponding factors are (w + 4)(w^2 - 4w + 16).
Therefore,
(w^3 +64)/(4+ w) reduces as follows:
    (w^3 +64)/(4+ w)      (4 + w)(w^2 - 4w + 16)
 --------------------------- = --------------------------------- =  (w^2 - 4w + 16)
              4 + w                     4 + w
 
        
             
        
        
        
The answer is B when you subtract every like term
        
                    
             
        
        
        
You're nearly there. Just some more steps.
557 * x = 594 tells us 
x = 594 / 557 (divide both sides by 557)
x ≈ 1.066427
When we've found this number we must realise the following:
the '1' in this answer is the 100% the car fixing costs (without taxes)
the '0.66427' stands for the tax rate.
To find the tax rate we multiply 0.66427 by 100, which gives us:
0.66427 * 100 = 6.6427 ≈ 7
So, rounded to the nearest %, the tax rate is 7%
        
             
        
        
        
3/4 Of X(Capacity) = 18 Gallons
X = 18*4/3 
 = 6*4
 = 24 Gallons 
Capacity of Tank = 24Gallons
