Question

|2x+6|– 5х при х=-5

Answer 1

|2х+6|-5х при х=-5:

|2×(-5)+6|-5×(-5)=|-10+6|+25=4+25=29

Answer 2

To find the value of the expression $|2x+6| - 5x$ when $x = -5$, substitute $x = -5$ into the expression and evaluate it step by step:

$|2(-5) + 6| - 5(-5)$

Now, calculate the values within the absolute value and multiplication:

$|-4| - (-25)$

Since the absolute value of $-4$ is $4$, we can substitute it:

$4 - (-25)$

Now, subtract $(-25)$ from $4$:

$4 + 25 = 29$

So, when $x = -5$, $|2x+6| - 5x = 29$.
