Question

A greenhouse that specializes in growing carnations is divided into sections. The number of plants in each section depends on the number of sprinklers in that section.

There are y(5y − 4) red carnation plants and (9 + y)2 white carnation plants in a section with y sprinklers.

Which simplified expression represents the total number of red and white carnation plants in a section with y sprinklers?

Answer 1

So, basically are you looking for y, or are do you just need to make an expression?

Answer 2

Well, the options are 5y2 + 18y +77

5y4 + 14y + 81

6y2 + 14y + 81

6y2 + 18y + 77
but i already know the second one isn't it.

Answer 3

How do you know that?

Answer 4

Because My teacher said i got it wrong.

Answer 5

And she's making me do corrections

Answer 6

Okay

Answer 7

So what do i do?

Answer 8

So, by the looks of it, I think we should multiply the two.

Answer 9

By what

Answer 10

Multiply y(5y − 4) and (9 + y)2

Answer 11

Do that and tell me what you got :D

Answer 12

Okay hold on a sec

Answer 13

is the second one (9+y)^2?

Answer 14

\[(9+y)^2\]?

Answer 15

Is it gonna be long?

Answer 16

you just need to simplify the two equations separately amd "ADD" them, they just want the total number of carnations ..
So simplifying gives you \[5y^2-4y+81+18y+y^2=6y^2+14y+81\]

Answer 17

Yeah that

Answer 18

is it clear on how i get it?

Answer 19
