Line a is a perpendicular bisector of line segment k m. it intersects line segment k m at point l. line a also contains point n. line segment k l is 9 x +5. line segment k n is 14 x minus 3.
what is the length of segment lm?

__ units

the answer is 23

Step-by-step explanation:

f(1) = 10, f(2) = 17, f(3) = 24, f(4) = 31, f(5)=36, f(6)=45

Step-by-step explanation:

f(1) = 7(1) + 3     f(2) = 7(2) + 3   f(3) = 7(3) + 3    f(4) = 7(4) + 3   f(5) = 7(5) + 3

 f(1) = 7 + 3        f(2) = 14 + 3      f(3) = 21 + 3     f(4) = 28 + 3      f(5) = 35 + 3

   f(1) = 10             f(2) = 17            f(3) = 24            f(4) = 31            f(5) = 38

f(6)= 7(6) + 3

 f(6) = 42 + 3

    f(6) = 45
