The answer would be -7 n= -7 because a negative times a negative equals a postive
D.
This is because it is a question that involves doing actual math rather than just asking and getting an answer.
Answer: the answer is 7
Step-by-step explanation:
Area of quadrilateral= Length x Width
a+5 times a-2 = 60 which is the area
7+5 times 7-2= 60
12 times 5= 60
Therefore, a equals 7

Answer:
stationary time is 2 hours 30 minutes
Traveling time is 3 hours 30 minutes
Step-by-step explanation:
There are two distinct line types on the graph
the horizontal ones and the ones going towards the upper part
The horizontal ones represent the stationary positions while the climbing one represent the traveling time
The horizontal ones are;
3 to 3:30
4-5
6:30 to 7:30
Time here is ;
30
minutes + 1 hour + 1 hour = 2 hours 30 minutes
The traveling time;
2 - 3
3:30 to 4
5 to 6:30
7:30 to 8
1 + 30 min + 1hr 30 + 30
= 3 hours 30 minutes
