If ABCD is dilated by a factor of 2, you multiply the coordinates by 2. For the coordinate D', you would multiply 3 by 2 to get 6 and you would multiply -2 by 2 to get -4. Answer: (6, -4)
The answer is x=9. If you have to do inverse property on 4. Rhem combine like terms 7x and -4x. You'll get 3x=27, after that you divide 3 to both sides. As your answer x=9
