Пошаговое объяснение:

Answer 2

Let's break down the expression step by step:

1. Start with the parentheses: (-9, 18 : 3, 4 - 3, 7)

2. Inside the parentheses, you have a division (:) and a subtraction (4 - 3.7): (-9, 18 : 3, 0.3)

3. Perform the division: (-9, 18 / 0.3)

4. Now, calculate the division: (-9, 60)

5. Finally, multiply the result by 2.1: (-9, 60) * 2.1

Let's calculate the final result:

(-9, 60) * 2.1 = (-18.9, 126)

So, the result of the expression is (-18.9, 126).
