Answer:
11+6i
Step-by-step explanation:
We can start by combining like terms, the ones with i, and the ones with one as a factor. Since 3+8 is 11 and 4i+2i is 6i, our answer is C. 11+6i
Answer:
the answer is X=-8 or X= 2
Step-by-step explanation:
subtract 10 from both sides in order to eliminate 10.
x^2 + 6x -16
find two factors of -16 that sum up to 6.
-2 and 8 are two factors of -16 that sum up to 6.
(x-2)(x+8)
x-2= 0, x= 2
x+8= 0, x = -8
- - To find a "what number is x% of x"
You have to first change 35% into a decimal.
35%=0.35
Now 0.35*22=7.7
Therefore your final answer is 7.7
