By the intersecting chords theorem, you have
![7\cdot4=5\cdot x\implies 5x=28\implies\boxed{x=\dfrac{28}5}](https://tex.z-dn.net/?f=7%5Ccdot4%3D5%5Ccdot%20x%5Cimplies%205x%3D28%5Cimplies%5Cboxed%7Bx%3D%5Cdfrac%7B28%7D5%7D)

Answer:
To determine what is the difference between "6 + A" and "6 x A", the logic of the proposed mathematical operations must be explained:
In "6 + A", the value A is added to the initial value 6. Thus, for example, if A were worth 10, to the initial value 6 10 units are added, with which the final value is 16.
In contrast, in "6 x A", the initial value 6 is multiplied by as many times as the value A indicates. Therefore, continuing with the value of A as 10, in this case 6 would be multiplied by 10 times, giving a final value of 60.
