Answer:
2
Step-by-step explanation:
Range is the highest number of plots minus the lowest number, in this case it would be 3-1
|r+3| = (r+3) when r ≥ -3 so for r ≥ -3
r + 3 ≥ 7
r ≥ 4
|r+3| = -(r+3) when r < -3 so for r < -3
-(r + 3) ≥ 7
r + 3 ≤ -7
r ≤ -10
The answer to this question is r ≤ -10, r ≥ 4
23/ 4621 is 0.00497728, if you meant 4621/ 23 then it's 200.913043.
