There you go. Hope it help.
use this formula
Step-by-step explanation:
Use the distance formula.
d = √[(x2 - x1)2 + (y2 - y1)2]
You have all of the coordinates. Plug in the numbers and evaluate.
Divide b from both sides then it should be a equal C therefore if you add be it be the midpoint of a and C because BNB or equal to a C
its 1200 i think i work it out but i could have done it wrong
19) 5c+c=-6+2
6c=-4
c=-4/6
c=-2/3
20) -20-8=-2e
-28=-2e
28/2=e
14=e
21)p-2w=2l
(p-2w)/2=l
