The correct answer for this question is 11 - 13i.
This is how to answer this one:
(7 - 3i) (2 - i)
= [ (7*2) - (3i*2) - (7*i) + (3i*i) ]
Get the product of each term
= (14 -6i - 7i + 3i^2)
Group similar terms
= 14 - 13i - 3
Simplify.
= 11 - 13i
Side solution:
i = square root (-1)
i^2 = -1

Answer:
900 miles long
Step-by-step explanation:
Given data
Le the total mile of the trip be x
Autumn fell asleep at 39% of the trip, which is equal to 351 miles
so
=39/100*x= 351
0.39x= 351
divide both sides by 0.39
x= 351/0.39
x= 900 miles
Hence the trip is 900 miles long
