Answer 1

||-7+3|+7|=||-4|+7|=|4+7|=11

Answer 2

To find the value of the expression ||a+3|-a| when a = -7, let's substitute -7 into the expression:

||-7 + 3| - (-7)|

First, evaluate the inner absolute value:

|-7 + 3| = |-4| = 4

Now, evaluate the outer absolute value:

||-4| - (-7)| = |4 - (-7)| = |4 + 7| = |11| = 11

So, the value of the expression when a = -7 is 11.
