The answer is C because AO and BO are equal. And with AO being three times the length of CO, BO should be the length of DO
 
        
             
        
        
        
Answer:
4*x^4*y^22
Step-by-step explanation:
Your goal here is to REDUCE the given expression to simplest terms.
One way in which to approach this problem would be to rewrite (2x^2y^10)^3 as:  (2x^2*y^8)*y^2*(2x^2*y^10)^2.
Dividing this rewritten expression by 2x^2*y^8 results in:
y^2(2x^2*y^10)^2.
We now need to raise (2x^2*y^10) to the power 2.  Doing this, we get:
4x^4*y^20.
Multiply this by y^2 (see above):
y^2*4x^4*y^20
The first factor is 4:  4y^2*x^4*y^20.  This is followed by the product of y^2 and y^20:                   4*y^22*x^4
Finally, this should be re-written as 
                                     4*x^4*y^22
Another way of doing this problem would involve expanding the numerator fully and then cancelling out like factors:
8*x^6*y^30      4*x^4*y^22
----------------- = ------------------ = 4*x^4*y^22
   2x^2y^8                  1
 
        
             
        
        
        
The rule (x, y) ⇒ (x-2, y+3) will translate the way you want.
 
        
             
        
        
        
I am to believe that his score was 70.
since mike scored 15 less than 85 i had suspected it was 70
        
             
        
        
        
To estimate, you can round 627 up to 630 and round 253 down to 250. 
650-250=380. 380 is your estimate.
The actual answer is 374.
