Q. Is 22 a factor of 18u+918u + 9?\newlineChoices:\newline(A)yes\newline(B)no
  1. Factor out common term: Simplify the expression by factoring out the greatest common factor.\newline18u+918u + 9\newline= 9(2u+1)9(2u + 1)
  2. Check for divisibility: Check if 22 is a factor of the simplified expression 9(2u+1)9(2u + 1).\newlineSince 99 is not divisible by 22 and 2u+12u + 1 is an expression where 22 is a factor of 2u2u but not of the +1+1, 22 is not a factor of the entire expression 9(2u+1)9(2u + 1).
