Answer:



Step-by-step explanation:
Given



Rotation: 90 degrees clockwise
Required
Determine A'B'C'
When a point  is rotated 90 degrees in the clockwise direction, the new coordinates is:
 is rotated 90 degrees in the clockwise direction, the new coordinates is: 
So, we have:



Becomes



 
        
             
        
        
        
A (b-c)=d
ab-ac=d
ab-d=a.c
Divide both sides by a
Your answer = ab-d/a
Answer choice C
        
                    
             
        
        
        
1=81 centimetres 
1=82 centimetres 
2=83 centimetres 
3=84 centimetres 
1=85 centimetres
        
             
        
        
        
Answer:
scale factor P to Q: 4/5   scale factor Q to P: 5/4
Step-by-step explanation:
Divide original length over new length and you'll get the scale factor. 
 
        
             
        
        
        
Hiya!
Right now, both of their medians are 86. This means that both will get the same median if a 65 was added.
I believe A.) would be the correct answer, given it's pretty far away from 83 or 84. My second answer would be B.), but I'm not sure.
