Answer: The correct options are
(B) +11
(C) -11.
Step-by-step explanation: We are given to select the numbers from the options that are 11 units from 0 on the number line.
We know that
the distance between a and b on the number line is given by
[tex]D=b-a,[/tex] where b is greater than a.
So, we have
the distance between 0 and 0 on the number line is
[tex]D=0-0=0~\textup{units}.[/tex]
The distance between +11 and 0 is
[tex]D=+11-0=11~\textup{units}.[/tex]
The distance between -11 and 0 is
[tex]D=0-(-11)=11.[/tex]
Thus, the required numbers that are 11 units from 0 are +11 and -11.
Options (B) and (C) are CORRECT.
