4. A biologist studied the populations of common guppies and Endler's guppies over a 6-year period. The biologist modeled the populations, in tens of thousands, with the following polynomials where x is time, in years.
Common guppies: 3.1x^2 + 6x + 0.3
Endler's guppies: 4.2x^2 - 5.2 + 1
What polynomial models the total number of common and Endler's guppies?

A. 7.3x^2 + 0.8x + 0.7.
B. 7.3x^2 - 0.8x + 1.3.
C. 7.3x^2 + 0.8x + 1.3.***
D. 7.3x^2 + 0.8x - 1.3.
4x^10+9x^10
Show your work
4x^10 + 9x^10 = (4 + 9)x^10 = 13x^10
Therefore, the sum of 4x^10 and 9x^10 is 13x^10.
