lina2011 [118]

Answer:  d. 3

Step-by-step explanation:

By the The intersecting chords theorem,

x(x+3) = 2\times 9

\implies x^2+3x=18

\implies x^2+3x-18=0

\implies x^2+6x-3x-18=0    

\implies x(x+6)-3(x+6)=0

\implies (x-3)(x+6)=0

\text{ if }x-3=0\implies x = 3

or \text{ if }x+6=0\implies x = -6 ( can not possible)

Hence, x = 3

⇒ Option d is correct.
