Use absolute value to express the distance between −12 and −15 on the number line

The distance between -12 and -15 is 3.

Step-by-step explanation:

The absolute value is utilized to calculate distance. The definition of absolute does not include the sign, and the symbol used to indicate absolute values is |X|, where X mens the value or the formula. For example, the absolute value of 5 is 5 (|5|=5) and the absolute value of -5 is also 5 (|-5|=5); in this case it refers to the distance from 0.  

The formula for this exercise is Distance = |-12 – (-15)|

Distance = |-12 +15|

Distance = |3|

Distance = 3

Using absolute value, you can calculate the distance also inverting the values, for example:

Distance = |-15 – (-12)|

Distance = |-15 +12|

Distance = |-3|

Distance = 3

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
