Question

|| a+11 | -a | a= -10

Answer 1

Ответ:

11

Объяснение:

|x|=x если x>=0

|x|=-x если x>=0

a=-10: || a+11 | -a |=|| (-10)+11 | -(-10) |=||1|+10|=|1+10|=|11|=11

Answer 2

To evaluate the expression ||a+11| - |a|| when a = -10, follow these steps:

1. Replace "a" with -10 in the expression: ||-10 + 11| - |-10||

2. Perform the operations inside the absolute value signs: ||1 - |-10||

3. Calculate the absolute values: |1 - 10|

4. Perform the subtraction inside the absolute value: |1 - 10| = |-9| = 9

So, the value of the expression ||a+11| - |a|| when a = -10 is 9.
