So,
Using Intersecting Secants Theorem, we get
Divide both sides by 4.
Since, x = 11; PR = 12; PT = 15, therefore the correct option is C.
For this case we must simplify the following expression:
By definition of the law of multiplication signs we have to:
Rewriting the expression we have:
We add similar terms taking into account that:
Equal signs are added and the same sign is placed.
