Question

3×(х+10)=3х+10? Чи правильно виконано розкритя дужок

Answer 1

Ответ:

Нет.

Пошаговое объяснение:

Задание: Проверь, правильно ли раскрыты скобки: 3(х+10)=3х+10.

Решение: Воспользуемся распределительным законом умножения: а(b+c)=ab+ac. Тогда, 3(х+10)=3·х+3·10=3х+30. Поскольку 3х+30≠3х+10, значит скобки раскрыты неверно.

Answer 2

Відповідь:

Ні

Покрокове пояснення:

Перемножуємо на кожне число

3*(x+10)=3x+30

Answer 3

Simplifying the Expression

To determine if the expression 3×(х+10)=3х+10 is simplified correctly, let's simplify both sides of the equation and compare them.

On the left side of the equation, we have 3×(х+10). To simplify this, we distribute the 3 to both terms inside the parentheses:

3×(х+10) = 3×х + 3×10 = 3х + 30

On the right side of the equation, we have 3х + 10.

Comparing the simplified expressions on both sides, we can see that they are not equal. The left side simplifies to 3х + 30, while the right side is 3х + 10.

Therefore, the expression 3×(х+10)=3х+10 is not simplified correctly.

Correct Simplification

To simplify the expression correctly, we need to distribute the 3 to both terms inside the parentheses:

3×(х+10) = 3×х + 3×10 = 3х + 30

So, the correct simplified form of the expression 3×(х+10) is 3х + 30.

Conclusion

The expression 3×(х+10)=3х+10 is not simplified correctly. The correct simplified form is 3х + 30.
