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

Question

undeadknight26 · Answer

A company distributes free pencils to all the students of x schools. Each school has (x + 3) classes. The number of students in each class is 4 more than the number of classes in each school. Each student is given (x + 1) pencils.

I put:
You would solve:(x + 3) + 4 .

But that is not an equation @undeadknight26  !

-_-
i suck at math sorry...

math&ing001 · Answer

Also there's something missing in your problem. I think it's the number of free pencils is what's missing.

undeadknight26 · Answer

then we would have to solve this right?
(x + 3) + 4 = x + 7

math&ing001 · Answer

That statement is always true. Like I said before, there's some data missing from your problem. Check it again !

A company distributes free pencils to all the students of x schools. Each school has (x + 3) classes. The number of students in each class is 4 more than the number of classes in each school. Each student is given (x + 1) pencils.

Part A: Write an expression to show the total number of pencils distributed by the company in x schools.

Part B: What does x(x + 3) 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

x+3 classes / 1 school x+3+4 students / 1 class x+1 pencils / 1 student x schools 

A: x schools * [ (x+3)classes / 1 school ] * [ (x+3)+4 students / 1 class ] * [ (x+1) pencils / 1 student ]

math&ing001 · Answer

That makes more sense, because they're only asking for the expression and not a numerical result.
So the expression that shows the total number of pencils distributed by the company in x schools is the number of schools multiplied by the number of classes multiplied by the number of students multiplied by the number of pencils given to each student, which would be: x(x+3)(x+7)(x+1)

undeadknight26 · Answer

x^4 + 11 + x^3 + 31x^2  + 21???

math&ing001 · Answer

If you simplify, you would get : x^4 + 11x^3 + 31x^2  + 21x
