Answer 1

x equals six and two thirds

Answer 2

Answer: second option.

Explanation:

According to the Intersecting Secants Theorem, the products of the segments of two secants that intersect each other outside a circle, are equal.

Then, we know that:

`(4)(4+5)=(3)(3+x)`

Having this expression, we need to solve for "x" in order to find its value.

Then, this is:

`(4)(4+5)=(3)(3+x)\\\\(4)(9)=9+3x\\\\36=9+3x\\\\36-9=3x\\\\25=3x\\\\x=(27)/(3)\\\\x=9`
