Question

6(7a-4c)-(5a+2c)+(8a-4c

Answer 1

Ответ:

6(7a-4c)-(5a+2c)+(8a-4c)=42а-24с-5а-2с+8а-4с= 42а-5а+8а-24с-2с-4с=45а-30с

Можно вынести общий множитель: 5*(9а-6с)

Answer 2

To simplify the expression, let's start by distributing the multiplication and then combine like terms:

6(7a - 4c) - (5a + 2c) + (8a - 4c)

= 42a - 24c - 5a - 2c + 8a - 4c

Now, let's combine the like terms:

(42a - 5a + 8a) + (-24c - 2c - 4c)

= 45a - 30c

Therefore, the simplified expression is 45a - 30c.
