Answer 1

-6×0,5×4-8×0,5×-2-6×0,5×4=-16

Answer 2

-6×0,5×4-8×0,5×-2-6×0,5×4=-16

ответ 16

Answer 3

To evaluate the expression "Man-6mn^2-8mn-6mn^2" when m=0.5 and n=-2, we can simply substitute the given values of m and n into the expression and calculate the result.

Let's do that step by step:

1. Replace "m" with 0.5: Man = 0.5 * a * n = 0.5 * a * (-2) = -a

2. Replace "n" with -2: -6mn^2 = -6 * 0.5 * (-2)^2 = -6 * 0.5 * 4 = -6 * 2 = -12

3. Replace "m" with 0.5 and "n" with -2: -8mn = -8 * 0.5 * (-2) = -8 * (-1) = 8

4. Replace "m" with 0.5: -6mn^2 = -6 * 0.5 * (-2)^2 = -6 * 0.5 * 4 = -6 * 2 = -12

Now, let's put it all together:

Man - 6mn^2 - 8mn - 6mn^2 = -a - 12 - 8 + (-12)

Since we don't have specific values for "a," we can't calculate the final numerical result. The answer would be in terms of "a." If you have the value of "a," you can substitute it in to get the exact result.
