Answer:
1. -3 on both side and m=4
2. +2 on both side and k=10
3. divide 3 on both side and n=6
The answer to this is step 2 because they multiplied when they should of subtracted the 10 and the 12.
Common solution for each problem:
let
1st point=(x1,y1)
&,
2nd point=(x2,y2),then,
distance between 1st and 2nd point is:
√[(x2-x1)²+(y2-y1)²]
Just replace these x2,y2,x1,y1 with given points and you will get required answer..
