You need to tell us whether these numbers have to be added together or whether other mathematical processes can be used, e.g. -, /, x.
Just go for 4 x 5 = 20. The simple solutions are best

One yard equals 0.9144 meter. Therefore 20 yards = 20 * 0.9144 = 18.288 meters
Ralph only likes squares of numbers. He likes 25 (5 squared), 400 (20 squared), and 144 (12 squared).
That doesn't equate. That doesn't equate.
800N/2m^2 = 400N/m^2
(-20) degrees Celsius = -4 degrees Fahrenheit.
20
'20 squared' simply means 20 multiplied by itself (20 x 20). This equals 400.
Simple. When a number is 'squared' it simply means it is multiplied by itself. So, '20 squared' means 20 x 20, which equals 400.

100+20+1
the exponent is 2, expressed as twenty, squared or 20 X 20.
x2 - x = 20 x = 5
4, -5
If you mean: x2+9x+20 then it is (x+4)(x+5) = 0 when factored
5x2 - 20 = 0x2 - 4 = 0x2 = 4x = +2 and -2
(x+4)(x-5) = 0
The solutions are: x = 4, y = 2 and x = -4, y = -2
