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.

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

Part C: How can you calculate the total number of students in each school?

anonymous · Answer

number of school =x
number of classes of each school=(x+2)
total number of classes=x(x+2)

anonymous · Answer

number of student= (x-1)
total number of students= x(x+2)(x-1)

anonymous · Answer

i hope that you got the idea....

anonymous · Answer

So would I multiply  x(x+2)(x-1) by (x-2)?

i have something to do now but i will be back
yes
