Answer 1

Сначала преобразуем вторую скобку: 3а минус 7а равно минус 4а. Затем умножаем буквы с коэффициентами на скобки и всё

Answer 2

It looks like you've provided a mathematical expression:

2abc(3 - 2a) + 4b(3a - 7a)

Let's simplify this expression step by step:

1. Distribute the terms inside the parentheses: = 2abc * 3 - 2abc * 2a + 4b * 3a - 4b * 7a

2. Multiply the constants with their respective terms: = 6abc - 4a^2bc + 12ab - 28ab

3. Combine like terms: = 6abc + 12ab - 4a^2bc - 28ab

4. Combine the terms with "ab": = 6abc - 16ab - 4a^2bc

So, the simplified form of the expression is 6abc - 16ab - 4a^2bc.
