Answer 2

To evaluate the expressions you provided:

1. -20x * 0.05y:

To multiply two terms, you simply multiply the coefficients (numbers) and combine the variables with the same base. In this case, we have -20x and 0.05y.

Multiply the coefficients: -20 * 0.05 = -1

Combine the variables: x * y = xy

Therefore, the expression -20x * 0.05y simplifies to -xy.

2. 3ac * 4bc:

Similarly, we'll multiply the coefficients and combine the variables.

Multiply the coefficients: 3 * 4 = 12

Combine the variables: a * a = a^2 and c * b = cb

Therefore, the expression 3ac * 4bc simplifies to 12a^2cb.

Please note that the results provided assume standard algebraic conventions and the variables are not further specified in the context of their exponents or possible constraints.
