kelseybuell 3 years ago 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?

1. GOODMAN

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

2. kelseybuell

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.

3. GOODMAN

How do you know that?

4. kelseybuell

Because My teacher said i got it wrong.

5. kelseybuell

And she's making me do corrections

6. GOODMAN

Okay

7. kelseybuell

So what do i do?

8. GOODMAN

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

9. kelseybuell

By what

10. GOODMAN

Multiply y(5y − 4) and (9 + y)2

11. GOODMAN

Do that and tell me what you got :D

12. kelseybuell

Okay hold on a sec

13. Akshay_Budhkar

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

14. Akshay_Budhkar

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

15. kelseybuell

Is it gonna be long?

16. Akshay_Budhkar

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

17. kelseybuell

Yeah that

18. Akshay_Budhkar

is it clear on how i get it?

19. kelseybuell

GOODMAN?

20. GOODMAN

yea, still here, Akshay did it correctly.

21. kelseybuell

22. GOODMAN

Hahaha, Akshay did it, right up there, 6y2 + 14y + 81

23. kelseybuell

Thankyou!

Your daily workout plan involves a total of 60 minutes of jogging and biking. You burn 10 calories per minute jogging and 5 calories per minute biking. How many calories will you burn in your 60−minute workout if you jog for 30 minutes?

25. GOODMAN

Thank Akshay :D give him a medal!

26. kelseybuell

Is that 300?
