47 -14i
You can work this out in the straight-forward way, or you can recognize that (6-i) is a common factor. In the latter case, you have ...
... = (6-i)(5 + 3-i)
... = (6 -i)(8 -i)
This product of binomials is found in the usual way. Each term of one factor is multiplied by each term of the other factor and the results summed. Of course, i = √-1, so i² = -1.
... = 6·8 -6i -8i +i²
... = 48 -14i -1
... =

A suitable graphing calculator will work these complex number problems easily.
Hey, this is not a complete question, there is not visible graph. You may wanna retry to set up your question and make sure the graph is there
These are two problems that fit in that description 10+(-2) AND 15+(-7)
So you want to multiply 185.5 by 1.04 to get the 4% inflation. if you do that then you get 192.92
