2 complex figures. A corresponds to 18 centimeters, B corresponds to 24 centimeters, and a side with length 14 meters corresponds to a side with length 42 feet. What can be concluded about the scale factor and missing measures? Check all that apply. The scale factor is 3. The scale factor is One-third. Add the scale factor to 18 and 24 to find A and B’s lengths. Subtract the scale factor from 18 and 24 to find A and B’s lengths. Multiply 18 and the scale factor to find A’s length. Divide 24 by the scale factor to find B’s length.
