Answer 1

Ответ:

Пошаговое объяснение:

||a+3|-a|=||-7+3|-(-7)|=|| -4| + 7|=|4+7|=|11|=11

Answer 2

Let's evaluate the expression step by step:

1. |a + 3|: Substitute a = -7 |-7 + 3| = |-4| = 4

2. -|a|: Substitute a = -7 -|-7| = -|-7| = -7

Now, combine the results:

|a + 3| - |a| = 4 - (-7) = 4 + 7 = 11

So, when a = -7, the value of the expression |a + 3| - |a| is 11.
