<h2>there s a theorem called MIDPOINT THEOREM </h2>

Which means the 3rd side of the triangle is equal to 1/2 of the line drawn by joining the mid points

<h2>so AB=1/2of YZ</h2>

which means

2x-4 = 1/2×21

thus, 2(2x-4) =21

=> 4x-8 = 21

4x = 29

<h2>x= 29/4 = 7.25</h2>

Question:<br><br>|x-2|, if x &gt; 5<br> simplify without the absolute value sign
nikitadnepr [17]

Answer:

x - 2, if x > 5

Step-by-step explanation:

The vertical lines either side of the expression mean absolute value.

The absolute value of a number is its <u>positive numerical value</u>.

if x > 5 then as 5 > 2, the values inside the vertical lines will always be positive.  Therefore, we can disregard the absolute value.

Therefore:  

x - 2,  if x > 5

To find the range (output values) of the expression, substitute x = 5 into the expression:

⇒ 5 - 2 = 3

Therefore, |x - 2| > 3,  if x > 5
