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.

Answer:
-2x-2y=-8
-4x-8y=-20
From the 1st eqn
Dividing through by 2
you have
-x-y=-4
Multiply through by -(minus)
x+y=4
x=4-y
Substitute into eqn 2
-4x-8y=-20
-4(4-y)-8y=-20
-16 + 4y - 8y = -20
-4y = -20 +16
-4y = -4
y= 1
Substitute into any of the other eqn's to get x
x= 4-y
x= 4-1
x=3
I believe what you are wanting is f(x)= x+5.
So you have to add all the numbers to get the perimeter or the outside distance but it looks like t and s is there a few times so that’s were you have to simplify.
So here’s the answer simplified
4t+2s+w+v+x+u
Good luck!
