By geometric mean theorem:
Length of altitude

Answer:
16 and -4
Step-by-step explanation:
Let the 2 numbers be x and y with x > y
x+y=12
x-y=20
Adding the 2 equations, term by term on both sides, will eliminate y leaving an equation in x that we can solve
(x+x)+(-y+y)=(12+20)
2x=32
x=16
16+y=12
y=-4
16+-4=12
12=12
16--4=20
20=20
The inverse is the exact opposite so -11, -13 and it if was negative points to plot it would just be possible.
Only if it's an even number.
