The transformation is a reflection in the line
followed by a reflection in the line
.
The mapping for a reflection in the line
is
.
That is simply swapping the coordinates.
Now we reflect the resulting coordinates in the line
which has the mapping
So we transform the resulting coordinates as follows:
Hence we have
1. To find the length of the edge, you will divide the total distance of 36 cm between the 4 edges that are shown.
36/4 = 9 cm per edge.
2. To find the surface area, find the area of one square (9 cm x 9 cm = 81 square cm), and multiply it by 6.
81 square cm x 6 = 486 square cm
486 square cm is the surface area.

Answer:
166
Step-by-step explanation:
Put the given information into the formula and solve for p.
17.97 = 0.07p +11.25
6.72 = 0.07p . . . . . . . . . . . subtract the subscription fee
6.72/0.07 = p = 96 . . . . . . divide by the per-page charge
