SA= 2x(9+6+6)
=2x21 = 42 square centimeters
w = 
collect the term in w together → ( subtract 2w from both sides)
y - aw - 2w = - 1 → ( subtract y from both sides)
- aw - 2w = - 1 - y → ( multiply through by (- 1) )
aw + 2w = 1 + y → ( take out w as a common factor )
w( a + 2)= 1 + y → ( divide both sides by (a + 2 ) )
w = 
Answer:
Function is always a relation because otherwise an equation could not be written about its spread behavior.
Function cannot have two ys to an x. So, a relation is not always a function.
