Answer: (-6, 5)
<u>Step-by-step explanation:</u>
Use the Midpoint Formula: 
Separate the x's and y's and solve them individually:

So, the k-coordinate is (-6, 5)

<span>Algebraic expression of product of 2 and the second
power of y
=> Algebraic expression is a combination of integers (numbers), variables (a,
b, c, x, y, ….), exponent (2 5 3 …) that is a rational number and algebraic
operations like subtraction (-), addition (+), multiplication (x) and division
(/).
=> Product – result of multiplication
=> second power of y = y<span>2
</span>=> 2 x y<span>2
</span>Thus, the algebraic expression of product of 2 and the second power of y
is equals to 2 x y2

The last one would be negative.
Positive times positive = positive
Positive times negative = negative
Negative times negative = positive
So basically, if there is an odd number of negatives, then it'll end up negative, with some exceptions.
So now we know it has to either be the first one or the last one.
The first one is multiplied by 0, so it can't be that one.
So it has to be the last one.
