Answer:
1
Step-by-step explanation:
Let us consider the case of 3 numbers: x, y, and z.
Then x/x+y+z + y/x+y+z + z/x+y+z = x+y+z/x+y+z = 1
The same works also for any quantity of numbers.
Answer:
C
Step-by-step explanation:
The range is the values of y that extend from the vertex downwards
The vertex = (- 2, - 1) → y = - 1
range is (- ∞, - 1 ]
If they want you to find the perimeter I guess you add all sides so 9+9+9+9+30 = 66
