Answer:

Step-by-step explanation:

smallest triangle 5.7/11,
medium triangle 11/x
5.7/11=11/x
x=11*11/5.7≈21.2 (longer leg of the medium triangle)
difference between 6 and 5.7 is 6-5.7=0.3 ,
screen going to be 0.3 feet less, than leg of the medium triangle that was found
21.2-0.3=20.9 ft

is correct
Therefore 
Step-by-step explanation:
Given polynomial is 
To factorise the given polynomial by taking out the common terms of the given polynomial :

( here 2y is GCF common term so taking outside the terms of the polynomial )
( now taking (-) outside )
Therefore 
Option D)
is correct
