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?

A- 5y2 + 18y +77

B- 5y4 + 14y + 81

C- 6y2 + 14y + 81

D- 6y2 + 18y + 77

wow a very long winded way of asking you to add 
$$y(5y − 4) +(9 + y)^2$$

anonymous · Answer

multiply out using the distributive property, get 
$$5y^2-4y+(9+y)(9+y)=5y^2-4y+81+18y+y^2$$ then combine like terms

do you see which one is the answer?
