The areas of a figure and its transformed image are the same. which transformation could not have been applied to the original figure to create the image?       a. rotation of 90b. reflection across a horizontal linec. dilation by a scale factor of 0.5d. translation down 4 and then right 1

The answer to this question is the dilation with a scale factor of 0.5.  With a rotation, the size of the figure stays exactly the same - it is just turned.  With the reflection, the size also remains the same, it will just be flipped down or up (over/across the x-axis).  And, a translation does also NOT change the size of the figure.  It only moves the figure to a new position.  The dilation will create a similar figure (same shape, but NOT the same size).  In this case, the new figure will have side lengths half of the original figure.

Multiply 9 and 67. then multiply 3 with 67. lastly the answer that you got for 9x67 is to be subtracted by the answer you got for 3x67

10.4 is the answer for you
