Answer:
#1
Segment addition:
- RS + ST = RT
- RS + 17 = 47
- RS = 47 - 17
- RS = 30 units
#2
There are two possibilities:
- G is to the left of E. Then G = 3 - 6 = -3
- G is to the right of E. Then G = 3 + 6 = 9
So possible coordinates of G are -3 or 9
#3
The length of the segment is the absolute value of the difference of the end point coordinates.
- AB = 4 - (-2) = 4 + 2 = 6 units
