Question

A company distributes free erasers to all the students of x schools. Each school has (x + 2) classes. The number of students in each class is 1 less than the number of classes in each school. Each student is given (x - 2) erasers.

Part A: Write an expression to show the total number of erasers distributed by the company in x schools. (4 points)

Part B: What would x(x + 2) represent? When simplified, what would be the DEGREE and classification of this expression? (4 points)

Part C: How can you calculate the total number of students in each school? (2 points)
Can someone help me?

Answer 1

I think that part A is: (x+2)-1(x-2)

B: x^2 +2x and degree of 3 and it is a binomial

I am not sure if I am right

Answer 2

Each school has (x + 2) classes

Answer 3

The number of students in each class is 1 less than the number of classes in each school

that makes the number of students in each class \(x+2-1=x+1\)

Answer 4

there are \(x+1\) students each given \(x-2\) erasers

Answer 5

that makes the total \((x+1)(x-2)\)

Answer 6

B is right

Answer 7

So to find the total number of students I just combine?

Answer 8

x^2 -2x +1x -2

Answer 9

x^2 - x - 2

Answer 10

actually i have no idea how to calculate the number of students

Answer 11

ok. thank you for your help

Answer 12

oh yes i do!!

Answer 13

(x + 2) classes. The number of students in each class is 1 less than the number of classes in each school.

Answer 14

that makes the total number of students \((x+2)(x+1)=x^2+3x+2\)
