Answer:
 30,240 ways
Step-by-step explanation:
This question is bothered on permutation. Permutation has to do with arrangement. 
If there are 10 computers and 5 students, the number of ways students will sit at the computers if no computer has more than one student can be expressed as;
10P5 = 10!/(10-5)!
10P5 = 10!/(5)!
10P5 = 10*9*8*7*6*5!/5!
10P5 = 10*9*8*7*6
10P5 = 30,240
Hence the number of ways is 30,240 ways
 
        
             
        
        
        
D. X=3cm
Since the triangles are similar, just set up a proportion to solve for x. 
4/8=x/6. Then just cross multiply and solve from there.
