Answer:
1. 17 units
2. 11 units
3. 14 units
Step-by-step explanation:
1. -8 is 8 units from 0, +9 is 9 units from zero. Distance is positive so 8+9 = 17
The same counts for the other two:
2. -4 is 4 units from 0, +7 is 7 units from zero. 4+7 = 11
3. -7 is 7 units from 0, +7 is 7 units from zero. 7+7 = 14
