The last number will either be 5 or 0. For example 15, or 20.
Attached below is a step by step process of arriving at the answer.
The other endpoint is (1, -17).
The midpoint formula is:

Using our midpoint and endpoint, we have:

For the first equation (to find the x-coordinate) we will multiply both sides by 2:

Subtract 11 from both sides:
12 - 11 = 11+x₂ - 11
1 = x₂
For the second equation (the y-coordinate) we multiply both sides by 2:

Add 5 to both sides:
-22+5 = -5+y₂ + 5
-17 = y₂
This means that (x₂, y₂) is at (1, -17).
Answer:
3 ft
Step-by-step explanation:
A cube is made of 6 equal faces each of which is a square with the same side length. The surface area of the cube is the surface area of one side multiplied by 6. We know the surface area is 54 so divide this by 6.
54/6 = 9 ft^2
Since the surface must be a square, take the square root of 9 which is 3 ft. The length of one edge of the cube is 3 ft.
