You're solving an equation approximating the number of farm.incidents in Wales and England between 1980-88.
F = 3500
3500 = 250x - 493000
3500 + 493000 = 250x
496500 = 250x
496500/250 = x
1986 = x
Scalene means uneven isosceles means two angles are even
There are 1000 millimetres in a litre, so 1800 ml is 1.8 litres. 3-1.8 is 1.2.
