Answer 1

Вот на фото ответ, но последний пример в вопросе составлен некорректно. Зачем там после скобок минус?

Answer 2

To solve the expressions, let's first assume the value of "d" is known. Then we can perform the calculations:

1. 58 - d + 20: Let's say d = 5 (you can replace this with any value you want for "d"):

58 - 5 + 20 = 73

2. 60 + d - 28: Using the same value of d = 5:

60 + 5 - 28 = 37

3. (30 + 12) - Again, using the value of d = 5:

(30 + 12) - 5 = 37

Note that the third expression seems to be incomplete. If there was something after the subtraction symbol "-", please provide the complete expression, and I'll be happy to help you solve it. If not, then the value of the third expression is 37 as shown above.
