Gwen is two years older than her cousin Julie. Aunt Jess is twice as old as uncle Mark. Julie’s age is 26 less than the sum of aunt Jess and uncle Mark’s ages. The twins are 2 years younger than one-third Gwen’s age. Mark celebrated his 8th birthday at the reunion 10 years ago

If mark celebrated his 8th birthday 10 years ago then mark is 18 years old. Jess is twice as old as mark so Jess is 36 years old. Julie is 26 less than mark and jess combined so Julie is 28 years old. Gwen is two years older than Julie so Gwen is 30 years old. The twins are 2 less than 1/3 of gwen so the twins are 8 years old

The new vertices are:

Step-by-step explanation:

The given vertices are

Rule for reflection about x axis is →.

So, →

     →

     →

     →

Now, new vertices after reflection about x axis are .

Rule for 90 degree rotation counter-clockwise is →.

So, →

     →

     →

     →

Therefore, the new rectangle after reflection about x axis and rotated 90 degrees counter-clockwise has the following vertices:
