Answer:
8
Step-by-step explanation:
If we assume the '17' is the hypotenuse ( the Q does not say)
then 15^2 + x^2 = 17^2 via the pythag theorem for right triangles
x = 8
Answer:
1) -95.
2) 15.
3) The conference center is on floor 5.

2) Substituting gives 
3) After going 4 floors down, we are on level -4. After going 9 floors up to the desired room, we are on level -4+9=5. So the conference center is on floor 5.
We can use the distance formula to find the distance between these points.
Distance formula: 
√(-5 - 6)² + (-3 - (-3))²
√121 = 11
The difference between the points is 11.
