Answer:
14
Step-by-step explanation:
 
        
             
        
        
        
H²+10h+21 = 0
h²+3h+7h+21 = 0
h(h+3)+7(h+3) = 0
(h+3)(h+7) = 0
h+3=0
h = -3
h+7=0
h=-7
        
             
        
        
        
Answer:
The line passing through the points (2, -14) and (4, -24)
Step-by-step explanation:
 
        
             
        
        
        

 is a right triangle with base length 1 and height 8, so the area of 

 is 

.
The average value of 

 over 

 is given by the ratio

The denominator is just the area of 

, which we already know. The average value is then simplified to

In the 

-plane, we can describe the region 

 as all points 

 that lie between the lines 

 and 

 (the lines which coincide with the triangle's base and hypotenuse, respectively), taking 

. So, the integral is given by, and evaluates to,
