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?

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

    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.

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

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

    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?
