Question

WILL GIVE MEDAL

A restaurant has x floors. The number of tables on each floor is 4 less than the number of floors. The number of chairs with each table is 1 less than the number of tables on each floor. The expression below shows the total number of chairs in the restaurant:

x(x - 4)(x - 5)

Part A: What does x(x - 4) represent? (4 points)

Part B: What type of polynomial is x(x - 4)(x - 5)? (3 points)

Part C: What is the degree of the polynomial x(x - 4)? (3 points)

Answer 1

@pooja195

Answer 2

x(x - 4)
u see (x - 4) is the no of table on each floor
and x is no of floors
so x(x - 4) is the total no of tables in the restaurant @Wxlfz

Answer 3

Thanks, I appreciate it. The other two are fairly simple, But im having trouble because it has no exponents and that's the way I was taught to tell the degree.

Answer 4

just sollve the equation
x(x - 4) (x - 5) = something like x^3 + ...

Answer 5

Would it be a 3rd degree binomial?

Answer 6

i think so.....not sure

Answer 7

which one u need?

Answer 8

B and C. I have an idea but I need conformation, I CANNOT get this question wrong. @waleedo212

Answer 9

ok

Answer 10

@aloud

Answer 11

for b u want it in factor form or when multiplied?

Answer 12

cuz if u want it multiplied its a trinomial

Answer 13

part c is 2 for sure

Answer 14

Im not so sure, Both would be great.

Answer 15

well if not multiplied i guess binomial but when multiplied trinomial

Answer 16

thanks.
