Answer
20
Step-by-step explanation:
-4*20=-80
-4+20=16
A). To go from ABCD to A'B'C'D' takes two transformations.
Step-1 : Reflect the original figure around the x-axis.
Step-2 : Slide the new figure 7 units to the right.
See the attached drawing. It shows the whole process
including the intermediate status and coordinates of
the four points after Step-1. You'll love it.
B). I looked up a definition of 'congruent'. It said that two figures
are congruent if they have have the same shape and size after
being moved, rotated,
or reflected. (I was worried about the
'reflected' part.)
The solution is approximately
x=0.479823 or
x=0.48

8 + 0.4 + 0.07 + 0.008 is your answer. But all you had to do is separate your numbers with working on the biggest number to the smallest number.
