-19

Пошаговое объяснение:

3*(-6)=-18

|-18+7|=|-11|=11

5*(-6)=-30

11+(-30)=-19

Answer 2

To find the value of the expression |3x+7|+5x when x = -6, you simply substitute -6 into the expression and evaluate it step by step.

Step 1: Replace x with -6 in the expression. |3(-6) + 7| + 5(-6)

Step 2: Simplify the expression inside the absolute value. |(-18) + 7| + 5(-6)

Step 3: Continue simplifying inside the absolute value. | -11 | + 5(-6)

Step 4: Calculate the absolute value. | -11 | = 11

Step 5: Final calculation. 11 + 5(-6)

Step 6: Multiply. 11 - 30

Step 7: Calculate the final result. -19

So, when x = -6, the expression |3x+7|+5x evaluates to -19.
