I believe the answer is C!
Answer:
(C)19
Step-by-step explanation:
The diagram is drawn and attached.
Using the intersecting chord theorem
SL X LT = JL X LK
x X 12 = 14(x-1)
12x=14x-14
12x-14x=-14
-2x=-14
x=7
Therefore:
ST= SL + LT
=x+12
=7+12
ST=19
The correct option is C
3(3b+2)=-30 perform indicated multiplication on left side...
9b+6=-30 subtract 6 from both sides
9b=-36 divide both sides by 9
b=-4
