Q. Is 33 a factor of 20c+1020c + 10?\newlineChoices:\newline(A)yes\newline(B)no
  1. Factor out common factor: Simplify the expression by factoring out the greatest common factor.\newline20c+1020c + 10 \newline= 10(2c+1)10(2c + 1)
  2. Check divisibility by 33: Check if 33 is a factor of the simplified expression 10(2c+1)10(2c + 1).\newlineSince 10=2×510 = 2 \times 5 and neither 22 nor 55 is divisible by 33, 1010 is not divisible by 33.\newlineAlso, 2c+12c + 1 does not contain the factor 33 unless 10(2c+1)10(2c + 1)00 is specifically set to make it so, which is not given.
