Answer:
13 minus 3x cubed
Step-by-step explanation:
In both cases,

(as a consequence of the interesecting secant-tangent theorem)
So we have
10.





(omit the negative solution because that would make at least one of AB or AD have negative length)
11.




(again, omit the solutions that would give a negative length for either AB or AD)
What is the answer to this wrok
My answer is a and c becuase they equal the same on each side
Combine your like terms: 5v + 5 = 5v +4
subtract the 5v and 4 from each side: 0 = 1
because 0

1, there is no solution
