Question

M-(-62 n)-(-2k) 11 12 -2x-7y-(-z) 13 a+(b-c)

Answer 1

Ответ:

1)m-62n-2k×11

2)12-2x-7y-z

3)13a+b-c

Answer 2

Let's simplify the given expressions:

1. M - (-62n) - (-2k) Simplifying the double negative and removing parentheses, we have: M + 62n + 2k

2. 11 + 12 - 2x - 7y - (-z) Simplifying the double negative and removing parentheses, we have: 11 + 12 - 2x - 7y + z

3. 13a + (b - c) We can distribute the 13 to both terms inside the parentheses: 13a + b - c

Please note that without specific values assigned to the variables M, n, k, x, y, z, a, b, and c, we can only simplify the expressions using basic arithmetic operations and removing parentheses.
