Answer: (4)

<em>4 Absolute vale means how many places a number is away from 0 "zero". The absolute value of </em><em>(-4)</em><em>, written as abs</em><em>(-4),</em><em> is equal to 4 because </em><em>-4</em>

Step-by-step explanation:  

To represent the absolute value of a number (or a variable), we write a vertical bar on either side of the number. For example, the absolute value of 4 is written as |4|.

Also, the absolute value of -4 is written as |-4|. As we discussed earlier, the absolute value results in a non-negative value all the time.

Kruka [31]

Answer:

24!

Step-by-step explanation:

I will refer the people to A,B,C, and D

24 is the answer.

4 choices for the first position.

3 choices for the second.

2 choices for the third.

1 for the fourth.

4*3*2*1=24

Here it is listed out where a,b,c,d are the 4 people:

abcd

abdc

acbd

acdb

adbc

adcb

bacd

badc

bcad

bcda

bdac

bdca

cabd

cadb

cbad

cbda

cdab

cdba

dabc

dacb

dbac

dbca

dcab

dcba

(of course, this assumes that there is a direction to the line, or a 'front' and a 'back'.  If direction doesn't matter then the answer is 12, since every combination above has a reverse.  e.g., abcd and dcba.  The list becomes:

abcd

abdc

acbd

acdb

adbc

adcb

bacd

badc

bcad

bdac

cabd

cbad

A rectangular park had a perimeter of 18 miles. It is 7 miles wide. What is the area of the park?
4vir4ik [10]
Perimeter = 18 miles
Perimeter = 2a + 2b
2a + 2b = 18

a = ?
b = 7

18 = 2a + 2*7
18 = 2a + 14
2a = 18 - 14
2a = 4
a = 2

Area = a * b
Area = 2 * 7 = 14 miles2
