length can be found using:  XY = |x - y|

6) PD = |P - D|  = |-7 - (-1)|   = |-7 + 1|   = |-6|   = 6

7) SK = |S - K|  = |17 - (-5)|   = |17 + 5|   = |22|   = 22

8) AB = |A - B|  

     8 = |-2 - B|  

8 = -2 - B         or      -8 = -2 - B

10 = -B              or       -6 = -B

-10 = B              or       6 = B

9) XY = |X - Y|  

     1  = |X - 0|  

     1  = |X|

1 = X               or         -1 = X
