What is the reason for the fourth and eighth steps in the proof?

In a class, there are 12 girls. if the ratio of boys to girls is 5: 4 how many boys are there in the class

What is the quotient? x+5/ 3x²+4x+5 © 3x2 – 11 + x + s 3x – 11 + 60 x + 5 o 3x2 - 11 - 50 x + 5 3x – 11 - - x + 5

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 + 4x + 5 = 0
