Question

Расположить в порядке убывания : -l-14l,-l30l,l-16l,-21,l-(-9)l

Answer 1

-l-14l = -14, -l30l = -30, l-16l = 16, -21, l-(-9)l = 9.

Ряд в порядке убывания: l-16l; l-(-9)l; -l-14l; -21; -l-14l; -l30l;

Answer 2

To arrange the given numbers in descending order, we need to first evaluate the absolute values and then sort them accordingly. Let's break it down step by step:

1. |-14| = 14
2. |-30| = 30
3. |-16| = 16
4. |-21| = 21
5. |-(-9)| = 9

Now we have the following numbers: 14, 30, 16, 21, 9.

Arranging them in descending order: 30, 21, 16, 14, 9.

So, the numbers in descending order are: 30, 21, 16, 14, 9.
