Answer:
The area of the trapezium is 
Step-by-step explanation:
Area of a trapezium:

This formula is valid if b1 and b2 are parallel and h is perpendicular to both.
Since the trapezium given in the problem satisfies those conditions, we use the formula with:
b1=15 cm
b2=7 cm
h=6.8 cm


The area of the trapezium is 
 
        
             
        
        
        
Answer:
39
Step-by-step explanation:
f(x)=17x
f(3)=17(3)
f(x)=51 
g(x)=4x
g(3)=4(3)
g(x)=12
f(x)-g(x)
51-12= 39
 
        
             
        
        
        
<span> The answer is is 4 times. </span>
<span>The reason it is 4 is because 3 times 4 is 12 and 12 is less than 14. If you did 3 quarters times 5, you would get 15, going over the limit.</span>
        
             
        
        
        



which means either 

 or 

. The equation has no solution, since 

 is always bounded between -1 and 1. The second has one solution at 

, and any number of complete revolutions will also satisfy this equation, so in general the solution would be 

 where 

 is any integer.
So you could choose 

 and 

.
