A biologist studied the populations of common guppies and Endler's guppies over a 6-year period. The biologist modeled the populations, in ten of thousands, with the following polynomials where x is time, in years. Common guppies: 3.1x^2 + 6x + 0.3Endler's guppies: 4.2x^2 - 5.2x + 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 - 1.35. A family is building a circular fountain in the backyard.
