8 0

Answer:

48

Step-by-step explanation:

The mean of a number is the sum of all the numbers divided by how many numbers there are. We can set up this formula: mean = \frac{sum}{amountnumbers}.

When we plug our values into this equation, we get: 6 = \frac{sum}{8}. Solving this equation gets us sum = 6 * 8 = 48

If (a+bi)^2=2abi, what must be the relationship between a and b? Show or explain your reasoning.
Klio2033 [76]
(a+bi)^2 =(a+bi)(a+bi)= a^2 +2abi+b^2 i^2 \\  \\ i^2 = -1 \\  \\ (a+bi)^2 = a^2-b^2 +2abi = 2abi \\  \\ a^2 -b^2 = 0 \\  \\ a^2 = b^2 \\  \\ a = b

For the statement to be true, 'a' and 'b' must be equal

*First expand the binomial using FOIL, then set it equal to whats given "2abi".
Then you can find the relationship between a and b.
