Evaluate the expression. |18 – 4| 22 14 –14 –22

Work Shown:

|18-4|

|14|

14

You subtract 18-4 to get 14. Applying absolute value on a positive number leads to the same result.

14

Step-by-step explanation:

|18 – 4|

First find the value inside the absolute value bars

18-4 is 14

|14|

Then take the non negative value

14

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1
