See how there are two rectangle prisms? Find the area of both of them separate, and then add the two answers together. 
Hope this helps!!
        
             
        
        
        
200, 100/200 Cups of Pretzels. 200, 100/400 Peanuts. 400, 100/200 Dry Cereal. 300/400 Cups of raisins.
        
             
        
        
        
Answer:
Step-by-step explanation:
Subset of A = { {} , {a} , {b}, {a.b} }
 
        
             
        
        
        
X = large boxes and y = small boxes
x + y = 70.....x = 70 - y
60x + 65y = 4300
60(70 - y) + 65y = 4300
4200 - 60y + 65y = 4300
5y = 4300 - 4200
5y = 100
y = 100/5
y = 20 <=== the small boxes weigh 20 lbs
x + y = 70
x + 20 = 70
x = 70 - 20
x = 50 <== and the large boxes weigh 50 lbs
        
             
        
        
        
Answer: the graph farthest to the right is almost correct. If you substitute values for x in the function f(x)= -3√x , the output does not match the curve on the graphs shown.
If you have a choice that includes only a curve to the right of the y- axis, that would be better. 
Step-by-step explanation: Square roots of Negative x-values will result in imaginary numbers. Otherwise the graph with the curve passing through coordinates (1,-3) (4,-6) and (9,-9) is a good choice. 
(And ask your teacher about the square root of negative numbers on this graph.)
