-3 represents the distance from a stage to the floor below. 3 represents the distance from the stage to the top of a bookcase. What dose zero represent in this situation?

the distance from the floor below to the top of the bookcase

Step-by-step explanation:

From the question we are given the following

distance from a stage to the floor below = -3

distance from the stage to the top of a bookcase = 3

The distance from the floor below to the top of the bookcase = distance from a stage to the floor below + distance from the stage to the top of a bookcase

The distance from the floor below to the top of the bookcase = -3 + 3

The distance from the floor below to the top of the bookcase = 0

Hence zero represents the distance from the floor below to the top of the bookcase

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
