Answer :
The correct answer is option C. -43 and 69.
The points 56 units away from 13 on a number line are -43 and 69. To find these, we add and subtract 56 units from 13. Thus, the answer is C -43 and 69.
To determine which points are 56 units away from the point located at 13 on a number line, we need to calculate both the positive and negative directions from this point.
Given point: 13
Distance: 56 units
Calculate points 56 units to the left and to the right of 13:
To the right: 13 + 56 = 69
To the left: 13 - 56 = -43
The points that are 56 units away from 13 are -43 and 69.
Therefore, the correct answer is: C. -43 and 69.
Well, one can take 13 and subtract 56 which is -43.
One can also add 56 to 13 to equal 69.
C is the answer.
