Answer:
see attached picture please
The square root of 20 is an irrational number because you cannot turn it into a fraction.
The number on the screenshot is the square root of 20. Because this number doesn't end or repeat, you can't make it a fraction, and therefore it's irrational.
First you need to find the X You know that since its a parallelogram opposite sides are congruent so you would do the following equation
(The work below goes vertical)
2x+3=3x-1
-3x-3I-3x-3
---------------
-x =-4
/-1 /-1
----------------
x= 4
So now that we know x=4 we plug it into the side
4+2=6
Then you multiply is by two since df goes across the whole shape and u get 12
Hope that helps
