Part A
The first thing we must do in this case is to hide the slopes of each line.
line m:
m = (- 4-3) / (0 - (- 4))
m = -7 / 4
Line n:
n = (- 2-2) / (3-1)
n = -4 / 2
n = -2
Answer:
Lines m and n are not parallel because their slopes are different.
Part B:
We look for the slope of the K line:
k = (1 - (- 3)) / (4 - (- 3))
k = 4/7
We observe that it is true that:
k = -1 / m
Answer:
The lines are perpendicular.
The highest common factor of 5, 3, and 4 is 60, so therefore the lights will flash at the same time after 60 seconds.

Please find the answer in the explanation.
Step-by-step explanation:
Given that Each toy box is in the shape of a cube. The total volume of the five toy boxes when placed in a row is 2,600 cubic inches.
If Claire thinks she will need about 40 inches of floor length for the toy boxes and Lucy thinks she will need about 45 inches of floor length for the toy boxes, one of them must be right.
Since Volume = L × B × h
Substitute the volume value and the length into the formula to know the area of the box. This must be in whole number and not in decimal number.
Area = 2600 / 40
Area = 65 square inches. For Claire.
Then for Lucy, we get:
Area = 2600 / 45
Area = 57.7778 square inches
We can therefore conclude that Claire is correct.
- 25 + 12 - 8 = - 21
if you get the $8 you owe them $21
