7+3+8+3=21 fishes in total
8/21 fishes are healthy
8/21 = 0.4 => 40%
F(x)......ur output = 19
19 = 2x^2 + 3x + 5
2x^2 + 3x + 5 - 19 = 0
2x^2 + 3x - 14 = 0
(2x + 7)(x - 2) = 0
2x + 7 = 0
2x = -7
x = -7/2
x - 2 = 0
x = 2
I believe there is 2 possible answers......x (ur input value) = -7/2 or 2
14/19 if you add the amount of nickels and dimes together and then for the denominator just add all of the coins together.
