Answer:
62
Step-by-step explanation:
There are two lengths so 77 + 77 is 154. Now, subtract from the perimeter. 278 minus 154 is 124. This is both widths combined so to only get one, divide by 2. 124 divided by 2 is 62.
The XY is dilated by a scale factor of 1.3 with the origin as the center of dilation to create the X'Y'. So the length of X'Y' is 1.3 times of origin but the slope is the same. The slope is m
To find the perfect square needed, you take the "middle" value and half it, then square it. so in this case, take -6, half it into 3, and square it to get 9. you'll be adding 9 to both sides
