7
Step-by-step explanation:
I need this to be 20 characters oof
The answer is 68/5 - 54/5i
-3(-x)-6=-3x+10
-3 -3
(-x)-6=-3x+7
-6 -6
(-x)=-3x+1
i only got this far!! im so sorry!!
I^2 = -1
i = √-1
Substitute the value of i in the equation:
(4+2i)(6-ki)=30
{4 + (2)(√-1)} {6 - k (√-1)} = 30
( 4 + 2√-1)(6 -k√-1) = 30
24 - 4k√-1 + 12√-1 -2k (-1) =30
24 - 4k√-1 + 12√-1 +2k =30
-4k√-1+12√-1 + 2k - 6 =0
-2√-1(2k -6) + (2k-6) =0
(-2√-1 +1)(2k-6)=0
2k -6 =0
2k = 6
k= 3
So, the value of k is 3.
Well, what you need to figure out is what times 9 is 63. That would be 7. So n=7 :)
