Ответ: B) -27

Answer 2

Let's simplify the expression step by step:

1. First, calculate the values inside the parentheses:

• Inside the first set of parentheses: 27 + 12 = 39
• Inside the second set of parentheses: 26 - 14 = 12

So the expression becomes:

• (39) + (12)

2. Now, add the two results together:

39 + 12 = 51

So the simplified expression is:

51

So, the correct answer is г) 29 is incorrect.
