Answer:
The length of SU is 25.
Explanation:
This is because distance is never negative. S is located on -15, U is located on 10. To solve this, you must add the inverse (or absolute value) of -15, which is a positive 15 to the value of U. Add the two numbers together, 15 + 10 = 25, and you've got the absolute distance.
