The height of each story in a hotel is 11 1/2 feet. the height is measured from the ceiling to the floor. the hotel has 2 underground levels that are used as banquet halls. stephen is a waiter who works two levels below ground. at what elevation are stephen’s feet? assume the ground level of the hotel is at 0 feet.

Stephen is at -23 feet below the ground level.

Step-by-step explanation:

Height of each story in a hotel is given as feet or 11.5 feet.

Hotel has 2 underground levels having same height of each level.

Total height of underground levels = 2 × 11.5 = 23 feet

Since ground level of the hotel is assumed to be at 0 feet.

Below this level all elevations will be with negative notation.

Therefore, Stephen will be working at the elevation = 0 - 23 = -23 feet

3x^3-x^2+6x-9

the correct is answer is a 9-sided polygon!
