Answer:
d
Step-by-step explanation:
if 2 chords of a circle intersect , then the product of the parts of one chord is equal to the product of the parts of the other chord, that is
KN × JN = LN × MN
(x - 4)(x + 23) = (x + 14)(x - 1) ← expand factors on both sides using FOIL
x² + 19x - 92 = x² + 13x - 14 ( subtract x² from both sides )
19x - 92 = 13x - 14 ( subtract 13x from both sides )
6x - 92 = - 14 ( add 92 to both sides )
6x = 78 ( divide both sides by 6 )
x = 13
