Question

3.х -6х + 15| при х=-7.​

Answer 1

Ответ:

-48

Объяснение:

3×(-7)-6×(-7)+15=-21-42+15=-48

Answer 2

To evaluate the expression 3x - 6x + 15 when x = -7, we substitute -7 into the expression for x:

3(-7) - 6(-7) + 15

Simplifying this expression, we have:

-21 + 42 + 15

Combining the like terms:

-21 + 42 + 15 = 36

Therefore, when x = -7, the value of the expression 3x - 6x + 15 is 36.
