<em><u>Before you read this!!</u></em><em> To me, it looks like 8 is the entire length of lineJL, but it may only be the length of lineJM. I've written the steps for lineJL=8 NOT lineJM=8. If this is not the case and 8 is only the length of lineJM let me know so I can fix my answer!</em>
Step-by-step explanation:
The area of a triangle is A=1/2(b)(h)
B=base
H=height
Your height is found in the line in the middle of the triangle, for you it is 6.
The base is the long bottom line on the triangle (lineJL), for you it is 8. 
So let's put it in. 
A=1/2(8)(6)
A=24sq units (C)
 
        
             
        
        
        
You take 45 and divide it by 15 and you get, 3 cubic feet
        
             
        
        
        
The most appropriate choice for function can be given by
q
p(3) =  
p
q(3) =  
What is function?
A function from A to B is a rule that maps to each element of A a unique element of B. 
A is called the domain of the function and B is called the co domain of the function.
We can do addition, subtraction, multiplication, division and composition on functions.
Let f and g be two functions
f
g(x) = f(g(x)) and g
f(x) = g(f(x))
This is known as composition of function.
Here,

q
p(x) = q(p(x))
           =
           = 
q
p(3) = 
           = 
p
q(x) = p(q(x))
           = p(
)
           = 
           = 
           = 
p
q(3) =
