You simplify it by doing distributive property like this
(4+2i)(3-i) =12-4i+6i-2i2
now add common like numbers
12+2i-2i2
Now on the i that is squared change the i to a -1 and get this
12+2i+2
Now again add common like numbers and get
14+2i that would be your answer
hope this helped
So far your getting all of them right. But, maybe next time upload a better picture because it’s hard to see what you wrote.

Answer:
1. w = nr
2. His wage is £52.00
Step-by-step explanation:
1. Given that wages is a function of number of hours worked multiplied by hourly rate
Where n represents hours and r represents rate.
Wage formula is as follows;
Wage (w) = hours (n) * rate (r)
w = n * r
w = nr
2. If he worked 5 hours at a rate of £10.40 per hour
This means
n = 5
r = 10.40
His wage is as follows;
w = nr
w = 5 * £10.40
w = £52.00
Hence, his wage is £52.00
