Electricity wasn't the only energy cost. also look at logs for fire. being that they were bought for fire it is using heat energy. there for making the total energy cost the highest. only look at what is energy cost toward the overall bill.
        
             
        
        
        
Step-by-step explanation:
volume = pi x radius² x height
okay so the cylinders diameter is 8 inches 
diameter divided by 2 is radius so 8/2 = 4
so 3 times the radius will be 3x4 = 12
use the formula above and then you will get your answer 
 
        
             
        
        
        
Answer:
The answer to your question is:
Step-by-step explanation:
                                              x² + 3x - 5
                                     x² + 3x + (3/2)² = 5 + (3/2)²
                                          (x + 3/2)² = 5 + 9/4
                                          (x + 3/2)² = (20 + 9) /4
                                           (x + 3/2)² = 29/4
                                           x + 3/2 = ±√29 / 2
                                      
 x 1 = -3/2 + √29/2                               x2 = -3/2 - √29/2
x1 = 1.19                                                x2 = -4.19
 
        
             
        
        
        
4x-5y=-15
That’s the answer your welcome
