U = 43.80 / 4
U = 10.95$
7 x 10.95 = 76.65$

Answer:
They are perpendicular because they have slopes that are opposite reciprocals of −2 and one half.
Step-by-step explanation:
This is because x = -2 and half of -2 is 1
when we use CD line and x2 we find 8x+4y=16 when added to 2x -4y=8 would equal 10x+4y = 2 1/2 xy = 16
When we use for AB line we see they are perpendicular 2 1/2 x 2 = 5 -4y = 8 shows y to be -2 and the 1/2 line leaves -2 1/2 and x also is 2 1/2.
