I’m pretty sure the answer is c.
Since each I guess ‘layer, or cubes will have 12 cubes.
The height is 4 
12*4=48
I hope this helps, I’m really sorry if the answer is wrong
        
                    
             
        
        
        
Peter's account is 910-40x, and Marla's account is 470-2x. This is a system, so you must find the number that makes both equations end up with the same number. Basically trial and error. Here is what I did:
Let's try the number 10. 910-400=510 and 470-20=450. I need a higher number. 
Let's try 13 next. 910-520=390 and 470-26=444. Now the number has to be lower. 
Let's try 12. 910-480=430 and 470-24=446. Close, and a little lower.
11.5 is too low, and 11.7 is too high.  11.6 has Equation 1 at 446 and Equation 2 at 446.8. Very close! 
It is somewhere around 11.6. I hope that this can give you a start in figuring it out, because I don't believe in giving the complete answer, because then you do not learn anything from it.
 
        
                    
             
        
        
        
Answer:
Otieno's age in 4 years: 
Kidole's age in 4 years: 
Step-by-step explanation:
 = Otieno's age
 = Otieno's age
 = Kidole's age
 = Kidole's age
Their ages will increase by 4 years when 4 years pass.
 = Otieno's age in 4 years
 = Otieno's age in 4 years
 = Kidole's age in 4 years
 = Kidole's age in 4 years
 = Kidole's age in 4 years (after simplifying the expression)
 = Kidole's age in 4 years (after simplifying the expression)
I hope this helps!
