The length of segments ab is 24
So we have the points (-5,1) for A and (0,6) for D. By using y=mx+b we can determine that y=x+6 which also can be rewritten as -x+y=6.
Since the string has already two 2, then we will compute the whole number of strings whose length is 4, over the alphabet {0,1}:

There is then 16 such strings.
Answer:A= - 1/5
Step-by-step explanation:
Multiply 17 x 3 to find the original number which is 51
then to check it you can divide 51 by 3 and you should get 17
