If you would like to solve the equation x^2 + 12 * x = -11, you can calculate this using the following steps:
x^2 + 12 * x = -11
<span>x^2 + 12 * x + 11 = 0
</span>(x + 1) * (x + 11) = 0
1. x = - 1
2. x = - 11
The correct result would be x = - 1, or x = - 11.

Answer:
2/9
Step-by-step explanation:
The question asks to calculate the number of boys in a group who has brown eyes given the fraction of the boys having the brown eyes.
To do this, we can take any arbitrary value for the total number of students in the math club. Let’s say this is 360 students.
Now, we are told that half of these number are boys. The total number of boys is thus 180 boys. Also, we are made to know that 4/9 of these boys have brown eyes. This means 4/9 of 180 boys have brown eyes. This is numerically equal to 4/9 * 180 = 80 boys.
Hence, the fraction of the math club with brown eyes is 80/360 = 2/9
