Abiologist studied the populations of white-sided jackrabbits and black-tailed jackrabbits over a 5-year period. the biologist modeled the populations, in thousands, with the following polynomials where x is time, in years.

white-sided jackrabbits: 5.5x² – 9.2x + 6.9
black-tailed jackrabbits: 5.5x² + 9.9x + 1.3

what polynomial models the total number of white-sided and black-tailed jackrabbits?

11x² + 0.7x + 8.2

11x² – 0.7x + 8.2

11x² – 0.7x – 8.2

–11x² + 0.7x – 8.2

Be in this im starting a with you so if you want you can get a partner for this. but basically im going to assign you guys a biome and you have to have a big sheet paper and you will turn it into 4 squares. the top right square is will be a drawing square for a drawing you will make of your biome. the top left square is about the biomes plants and drawings of them. the bottom left square is about the biomes animals. the bottem rights square is about the description of the biome. leave a comment or an answer and i will assign biomes. if your request one thats the one you get. send me a link to the project and i will grade ! im not a teacher btw.
