Question

Point B lies on segment AC . Find the length of the segment BC , if: AB = 4 mm, AC = 4 cm.

Answer 1

The length of the segment BC is 3.6

Explanation:

First you need to change 4 mm to .4 cm because mm and cm are not the same. So the total is 4 cm. but you only need to find BC. So in order to get BC, you do 4 - .04 which gives you 3.6. So the length of the segment BC is 3.6. There is a model if the explanation is not as clear.
