Answer:
D. 6x2^2y^2 + 10xy^2 - 2x^2y^3
Step-by-step explanation:
X represent the number of laps Marcy swam, 114x represent the number of times Toni swam.
20 + 0.80(114x) + 15 + 0.85x = 257
20 + 91.2x + 15 + 0.85x = 257
92.05x + 35 = 257
Required equation is 92.05x + 35 = 257

The squared variable is the "x", meaning is a vertical parabola.
the leading term, namely x², has a coefficient of -1, so is a negative value and thus it opens downwards.
i think it because when you rational X and witten the numer as a decimal hope i right just joke
example is rational number 4 12 then it say add and decimal the answer going to be 4.12
