Parallel lines mean that the slopes are the same, while perpendicular means that the slopes are negative reciprocals from each other.
With this information,
1. The slopes are the same, so PARALLEL.
2. The slopes are negative reciprocals, so PERPENDICULAR.
3. Same as the second.
Answer:
The perimeter =72
The width = 16
The length = 20
Step-by-step explanation:
.A rectangle has 4 sides , so 72 divided by four is 18. The question is that the width is 4 less than the length. The difference between the length and the width is 4 so increase the length by 2 and decrease the width by 2. Now the numbers obtained are 16 ( 18 decreased by 2) and 20 (18 increased by 2). It is mentioned in the question that the width is less and length is more.
R; all quadratic functions are going to have ranges and domains of *ALL REAL NUMBERS*.
