Answer:

189 students

Step-by-step explanation:

To solve this question, use the given values in the question and create an equation using these values. Make x = number of students.

2/9 of x (represents total number of students in school) is equal to 42, so create an equation for this.

  • 2/9x = 42

Divide both sides of the equation by 2/9.

  • x = 189

Since x represents the total number of students in the school, there are 189 students in the school.

x(x^2-7x-1) = 0

The factor inside the parenthesis cannot be factored

Since there is a common factor that we pulled out of the original equation,

set that x equal to zero and solve

x = 0\\ : Therefore x = 0
