Answer 1

Ответ: 15

я так понял это типа модуль, если да, то.

Пошаговое объяснение:

|-8-7|/ |-8+7|=

|-15|/ |-1 | =

модуль всегда положителен

15/1= 15

Answer 2

To find the value of |a - 7|/|a + 7| when a = -8, we can simply substitute the value of a into the expression.

Given: a = -8

Now, let's plug in the value of a into the expression |a - 7|/|a + 7|:

|(-8) - 7| / |(-8) + 7|

Simplify the expression inside the absolute value signs:

|-15| / |-1|

Now, calculate the absolute values:

| -15 | / | -1 |

The absolute value of -15 is 15, and the absolute value of -1 is 1:

15 / 1

Finally, the result is simply:

15

So, when a = -8, |a - 7|/|a + 7| equals 15.
