Answer 1

1)-84-2(-|6|-14)-19

2)-84-2(-6-14)-19

3)-84+12+28-19

4)-84+40-19

5)-43-19=-63.

Ответ : - 63

Answer 2

To compute the expression when x = -6, follow these steps:

Step 1: Replace x with -6 in the expression: 14x - 2(-|x| - 14) - 19

Replacing x with -6, we get: 14(-6) - 2(-|-6| - 14) - 19

Step 2: Simplify the absolute value expression: |-6| equals 6 because the absolute value of -6 is 6.

Now, the expression becomes: 14(-6) - 2(-6 - 14) - 19

Step 3: Continue simplifying: Calculate inside the parentheses first: 14(-6) - 2(-20) - 19

Next, perform the multiplications: -84 + 40 - 19

Step 4: Add and subtract: -84 + 40 - 19 = -43

So, the value of the expression when x = -6 is -43.
