Answer:
28 -4i
Step-by-step explanation:
Perhaps you want the product ...
(4 -2i)(6 +2i)
Multiplying in the usual way, we get ...
(4)(6) +(4)(+2i) +(-2i)(6) +(-2i)(2i)
= 24 +8i -12i -4i^2
Recognizing that i^2 = -1, we can collect terms to get ...
= 24 +i(8 -12) -4(-1)
= 28 -4i
_____
Please note that i = √(-1) is not the same as 1 or /. You may need to edit your question to ensure the correct symbol is used.
Hire firm:
200+0.50*1200 each month
200+600=800
lease truck:
350+480 each month
=830
so with contracting a firm instead of leasing trucks you would save 30$ each month or 30*12=360$ each year
