Answer 2

To evaluate the expression −1.26x + 88xy^2 + 48xy^2 when x = 3 and y = 0.1, we substitute the given values into the expression and perform the calculations.

−1.26x + 88xy^2 + 48xy^2 = −1.26(3) + 88(3)(0.1)^2 + 48(3)(0.1)^2 = −3.78 + 88(3)(0.01) + 48(3)(0.01) = −3.78 + 2.64 + 1.44 = 0.3

Therefore, when x = 3 and y = 0.1, the value of the expression −1.26x + 88xy^2 + 48xy^2 is 0.3.
