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

Step-by-step explanation:

Given: A biologist 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:

black-tailed jackrabbits:

The polynomial models the total number of white-sided and black-tailed jackrabbits is given by :-

Combining like terms we get,

Hence, the polynomial models the total number of white-sided and black-tailed jackrabbits is
