OB. 11 +78
O C. 6-12i
O D. 6+6i
Answer:
the correct answer is option B.
Step-by-step explanation:
First, we need to combine the terms inside the parentheses.
This gives us (8-3i)-(2-9i), or (8-3i)-(-2+9i).
We can then use the additive inverse property to simplify this to (8-3i)+2+9i, which is equal to (11+6i). Therefore, the correct answer is option B.
Answer:
4 hours and 15 minutes
Step-by-step explanation:
We have to find out how long it will take a driver to complete the route.
Time of start the route = 9:50 A.M.
Time of finish = 2:05 P.M.
We can convert the time of finish in 24 hours time
2:05 P.M = 14:05
Now we subtract start time from finish time.
14:05
- 09:50 [borrow 60 minutes to subtract 50 from 05]
04 : 15
It takes 4 hours and 15 minutes to drive the route.
