Please Help!!!! I think that the solution is d but I'm not sure.
A greenhouse that specializes in growing geraniums is divided into sections. The number of geranium pots in each section depends on the number of sprinklers in that section.
There are x(7x − 2) pots of red geraniums and (x + 3)^2 pots of pink geraniums in a section with x sprinklers.

Which simplified expression represents the total number of red and pink geranium pots in a section with x sprinklers? (4 points)
8x^2 + 4x + 9
8x^2 + 6x + 9
8x^2 + 6x + 7
8x^4 + 4x2 + 9
