With this question, i don't understand

  BC = 52

Step-by-step explanation:

The point of the question is to have you recognize and use the fact that the tangent segments from the same point are of equal length. That lets you write the equation ...

  4x +8 = 2(3x -7) . . . BC = BA

  2x +4 = 3x -7 . . . . . divide by 2

  11 = x . . . . . . . . . . . . add 7-2x

The length of segment BC is computed using this value of x:

  BC = 4x +8 = 4·11 +8

  BC = 52

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
