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:

The required equation is
T=6y^2+14y+81

Explanation:

Given : 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.

Red carnation plants =
y(5y-4)

White carnation plants =
(9+y)^2

with y sprinklers.

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

Solution :

Total number = Red carnation + White carnation plants


T=y(5y-4)+(9+y)^2

Now, we solve the equation


T=5y^2-4y+9^2+y^2+2\cdot 9\cdot y


T=5y^2-4y+81+y^2+18y


T=6y^2+14y+81

Therefore, The required equation is
T=6y^2+14y+81

The solution would be like this for this specific problem:

y(5y − 4) + (9 + y)²

Simplify the expression:

(5y² − 4y) + (81 + 18y + y²)

Combine the like terms:

6y² + 14y + 81

The simplified expression that represents the total number of red and white carnation plants in a section with y sprinklers is 6y² + 14y + 81. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.
