Question

6x-2(x+7) при x= 12 пж........

Answer 1

Ответ:

34

Пошаговое объяснение:

Раскрываем скобки:

6x - 2x - 14 = 4x - 14

Подставляем x = 12

4*12 - 14 = 34

Answer 2

Ответ:

34

Пошаговое объяснение:

Упростим:

6х-2х-14=4х-14

Теперь подставим 12:

4×12-14=48-14=34

Answer 3

To evaluate the expression 6x - 2(x + 7) when x = 12, we substitute the value of x into the expression and perform the calculations:

6(12) - 2(12 + 7)

First, we simplify the expression inside the parentheses:

6(12) - 2(19)

Next, we perform the multiplications:

72 - 38

Finally, we subtract 38 from 72:

72 - 38 = 34

Therefore, when x = 12, the value of the expression 6x - 2(x + 7) is 34.
