Question

Answer 1

Ответ:

$5 \alpha - 5 \beta + 60$

Answer 2

Let's simplify the expression step by step:

1. First, solve the innermost parentheses: 21 - 36 = -15

2. Now the expression becomes: 5(a - b) - 4(-15)

3. Distribute the coefficients outside the parentheses: 5a - 5b - (-60)

4. Simplify the double negative: 5a - 5b + 60

So, the simplified expression is: 5a - 5b + 60
