Answer:
Part A
2 hours 10 minutes
Part B;
Please find attached a number line created with MS Visio
Part C
The completed explanation is given as follows
The second showing starts at 7:35 p.m. The movie lasts 2 hours 10 minutes so it ends 9:45 p.m. So the second sowing be over by 9:45 p.m
Step-by-step explanation:
Part A
The given parameters are;
The time the first showing starts, t₁ = 4:35 p.m.
The time the first showing starts, t₂ = 7:15 p.m.
The time interval between shows, = 1/2 hours = 30 minutes
Let 'x' represent the video in minutes, we have;
x = 7:15 - 4:35 - 30 = 2 hours 40 minutes - 30 minutes = 2 hours 10 minutes
The length of the video = 2 hours 10 minutes
Part B;
Using the number line, we have;
1) Plotting the points for the starting and points for the two showing points which are 4:35 pm. and 7:15 p.m.
2) Plot the point 30 minutes before the start of the second movie which is 6:45 p.m and find the time difference between the start of the first showing and the point 6:45 p.m. which gives the length of the movie which is 2 hours and 10 minutes
3) Given that the second showing starts 20 minutes late, the second showing will start at 7:15 p.m. + 20 min = 7:35 p.m.
4) The second showing ends at 7:35 p.m. + 2 hours 10 minutes = 9:45 p.m.
Therefore, the second showing will be over 9:35 p.m.
Part C
The second showing starts at 7:35 p.m. The movie lasts 2 hours 10 minutes so it ends 9:45 p.m. So the second sowing be over by 9:45 p.m.

The left side is the difference of 2 squares,
so we know right away, without any uncertainty
or sweat, that it can be written as
(x + 5) (x - 5) ,
and we know that it's equal to zero when either factor is zero.
Now let's look at the choices:
A. X = -1 Not a chance.
B. X = -3 Also no.
C. X = -5 Yes that's good; that would make the first factor zero.
D. X = 5 Yes that's good too; it would make the second factor zero.
E. X = 3 Not true. Don't know how they came up with it.
F. X = 1 Equally not true.

m < 2 = 40
m < 2 + 90 + m < 3 = 180..(total of angles in a triangle are 180)
40 + 90 + <3 = 180
130 + <3 = 180
m < 3 = 180 - 130
m < 3 = 50
I assure you the answer is 50!
