All of the right triangles are similar.
.. (long side)/(short side) = 20/x = x/5
.. x^2 = 100 . . . . . . . . "cross multiply"
.. x = √100
.. x = 10
_____
The geometric mean of "a" and "b" is √(ab). x is the geometric mean of 20 and 5, the segments of the hypotenuse of the larger right triangle.
No it isn't.
16/C=4
Multiply c on both sides
16=4c
Divide 4 on both sides
Final Answer: 4=c
And so -4 is not the solution of this equation.
