X^2 = 16
x = 4
x = -4
good luck :)
So you have 20 people and 10 percent have brown eyes. So if 100% is 20, to find 10 percent you divide it by 10 to get 10% is 2. You know all the rest have hazel eyes so you just do 20-2 to get 18. Therefore 18 people have hazel eyes. Hope this helps :)
Answer:
Step-by-step explanation:
x^2 - 17x - 60
(x - 20)(x + 3)
x^2 + 3x - 20x - 60
x^2 - 17x - 60
(x + 20) is not one of the factors
using F.O.I.L., it would have been
x^2 + 17x - 60
