Answer 2

Ответ: откроем скобки 3*m*(3*m-m+1/2)=3m-3*m+m-1/2=m-1/2. Поставим значение 0,71-0,5=0,21.

Ответ 0,21.

Объяснение:

Answer 3

To evaluate the expression 3m - (3m - (m - 1/2)) when m = 0.71, you simply substitute the value of m into the expression and perform the calculations:

1. Replace m with 0.71 in the expression: 3(0.71) - (3(0.71) - (0.71 - 1/2))

2. Perform the calculations step by step: 3(0.71) = 2.13 0.71 - 1/2 = 0.21

3. Replace the results back into the expression: 2.13 - (2.13 - 0.21)

4. Continue with the calculations: 2.13 - 2.13 = 0 0 - 0.21 = -0.21

So, the final result of the expression when m = 0.71 is -0.21.
