Answer 3

a) To simplify the expression -2(3x + 0.2y - 6), you can distribute the -2 to each term inside the parentheses:

-2 * 3x + (-2) * 0.2y + (-2) * (-6)

This simplifies to:

-6x - 0.4y + 12

Therefore, the simplified expression is -6x - 0.4y + 12.

b) Similarly, to simplify the expression 0.4(-25y + 2x - 5), distribute 0.4 to each term inside the parentheses:

0.4 * (-25y) + 0.4 * 2x + 0.4 * (-5)

This simplifies to:

-10y + 0.8x - 2

Therefore, the simplified expression is -10y + 0.8x - 2.
