6.5𝑥^2 − 8.7𝑥 + 5.9 + 6.5𝑥^2 + 9.2𝑥 + 1.2
= (6.5+6.5) x^2 + (9.2-8.7) x +(5.9+1.2)
A biologist studied the populations of white-sided jackrabbits and black-tailed jackrabbits over a 5-year period. He modeled the populations, in thousands, with the following polynomials where 𝑥 is time, in years.
White-sided jackrabbits: 6.5𝑥^2 − 8.7𝑥 + 5.9
Black-sided jackrabbits: 6.5𝑥^2 + 9.2𝑥 + 1.2
What polynomial models the total number of white-sided and black-sided jackrabbits?

the answer is 11x^2+0.7x+8.2
Ben, ur answer is wrong bcz the reason u got is
white-sided jackrabbits: 5.5x² – 9.2x + 6.9
black-tailed jackrabbits: 5.5x² + 9.9x + 1.3
= 11x^2+0.7x+8.2
were talking abt
White-sided jackrabbits: 6.5𝑥^2 − 8. 7𝑥 + 5. 9
Black-sided jackrabbits: 6.5𝑥^2 + 9. 2𝑥 + 1. 2
white-sided jackrabbits: 5.5x² – 9.2x + 6.9
black-tailed jackrabbits: 5.5x² + 9.9x + 1.3
= 11x^2+0.7x+8.2

White-sided jackrabbits: 6.5𝑥^2 − 8. 7𝑥 + 5. 9
Black-sided jackrabbits: 6.5𝑥^2 + 9. 2𝑥 + 1. 2
