Question

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. (4 points)

Part B: What does x(x + 3) 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)

Answer 1

This is my last question. Anybody out there please help me. FAN and MEDAL

Answer 2

ok

Answer 3

@geerky42 come now, we have a prob

Answer 4

well, there is x schools and each school have x+3 classes. so for total of classes we have is x(x+3).

"The number of students in each class is 4 more than the number of classes in each school."
So let s be number of student in each class, so we have equation s = 4+(x+3)

we can combine like term and get s = x+7. so the total students is x(x+3)(x+7)

do you understand what I just did? can you figure the expression for total of pencils?

Answer 9

but I might be able to figure it out give me a min

Answer 10

@sourwing would it be 4+(x+3)(x+1)? for part a

Medals 1 a) x(x+3)(x+7)(x+1) = x^4+11x^3+31x^2+21x. If you're unsure of which, I'd include both.

b) (x+3) = classes per school, x = schools, so x(x+3) = total classes. x(x+3)=x^2+3x, degree 2 (greatest exponent).

c) Chop off the pencils per student in the original equation (drop "(x+1)"). x(x+3)(x+7) or x^3+10x^2+21x

I give credit to @tomhoe this is probably the correct answer
