Question

Essay question: show all work. Suzie's flower shop estimates that supplies costs for one month will be given by the polynomial 2x^2 +14x -9. She estimates that utilities costs for one month is given by 12x-3. Find and simplify an expression that would estimate Suzie's total costs for one month.

I would like to know the expression, I probably could work it out, I suck at word problems, so its hard for me to get an expression out of words.

Thank you for your help!

Answer 1

Two expression are both cost so to get total we get add the expression

Answer 2

Supply Cost = 2x^2+14x-9
Utilities cost = 12x-3
total cost = supply cost + utilities cost = 2x^2+14x-9+12x-3

Answer 3

ok so:
(2x^2+14x-9) +(12x-3)

Answer 4

right. you can add up the like terms. 14x+12x = 26x

Answer 5

So I have:
=(2x^2+14x-9) + (12x-3)
=2x^2+14x-9+12x-3
=2x^2+(14+12)x + (-9-3)
=2x^2+26x-12

Answer 6

yup

Answer 7

you can go one step further and factor out 2 to get 2(x^2+13x-6)

Answer 8

I don't know if i am suppose to. How would I know? I am doing polynomials.

Answer 9

it doesn't matter. The meaning of the polynomial has not changed. you can do it if you want or leave it alone.

Answer 10

ok, thanks again.

Answer 11

ok, thanks again.
