Find the measure of the dilated image of segment cd, 6 units long, with a scale factor of 3. a. one-third units b. 2 units c. one-ninth units d. 18 units

D, because if you apply a dilation of three to a line with a length of 6, you'd multiply the two, getting an answer of 18. You know to multiply since the scale factor is a number larger than 1

I’m not absolutely sure but i think it’s 7x6x5x4x3x2=5040 because as the first character you can take any of the 7 given then you are left with 5 then 6 then 4 etc.
