Id there are 21 girls according to my calculations there would be a heap amount of boys which is 23
E^x^2 - 9 = 1
e^x^2 = 1 + 9 = 10
Ln e^x^2 = Ln 10
x^2 = Ln 10
x = sqrt (Ln 10) = 1.517
x = 1.517
2×4=8 because 2 and 4 would be the addends and their less than 5 and it equal an answer between 4 and 10
