Answer:WY=24 hope this helps
Step-by-step explanation:refer the attachment
remember that,
the diagonals of Parallelogram bisect each other so WA=AY
thus our equation is
move left hand side expression to right hand side and change its sign:
rewrite 2x and 4x-6x:
factor out x:
factor out -6:
group:
recall that,
When the product of factors equals 0 then at least one factor is 0 so
since the length cannot be negative negative x isn't available
therefore
since WA and AY are the part of WY we acquire:
substitute the got value of x:
simplify square:
simplify multiplication:
simplify addition:
simplify substraction:
