Answer:
This is the commutative property of multiplication.
Step-by-step explanation:
We know this because that property states that it does not matter what order the numbers are multiplied together, as long as they are all being multiplied. So even though the numbers change on both sides, it does not affect the answer.
20-13=7 so your answer would be 7/20 I believe. Hope this helps!!
Option B: 
<u>Solution:</u>
<u>Slope of the perpendicular lines:</u>
If two lines are perpendicular then their slopes are negative reciprocals of each other.

<u>Slope of the parallel lines:</u>
If two lines are parallel then they have the same slope.
i.e their slopes are equal.

Given line m and p are parallel.
Slope of the line m = 
Using slope of the parallel lines definition,
Slope of the line p = slope of the line m
Slope of the line p = 
Option B is the correct aswer.
Hence the slope of the of line p is
