Answer:
A and B
Step-by-step explanation:
Parallel lines are lines which have the same slope. Perpendicular lines have negative reciprocal slopes.
For the options:
A. Both equations have 7/5 as the slope. They are parallel.
B. The slopes are 1 and -1. These are perpendicular.
C. The slopes are 9/2 and are parallel.
D. The slopes are 7/3 and -3/7. They are perpendicular.
The solution is A and B.
Given:
A rectangular piece of cloth (dimensions):
L = length of the rectangle
W = width of the rectangle
The area of the rectangle is:
A = L x W
If the cloth is cut along the diagonal, the area of one sail will be half the area of the rectangle:
A (one sail) = 1/2 (L x W) <span />

3-----4
Total (Left): 9
Total (Right): 12
-------------------
Total (Left) + Total (Right) = 9 + 12 = 21
What table? They can all be functions. I need to see a table.
