Answer: I really dont know sorry
Step-by-step explanation:
Answer:The answer would be the 13.5 by 1
That box means 90degrees so you put them equal to each other 90 = 15X
90/15 = 6
So x = 6
You want to isolate C, so the first step would to have it be positive. You would do this by adding C to both sides of the equation to cancel the C on one of the sides out like this:

. Then you want to cancel out the P, so you subtract it on both sides like this:

And that is your answer
Let g(x,y) be the midpoint of the segment ef;
So, x = (4+1)/2; then x = 5/2;
y = (-4+7)/2; then y = 3/2;
Finally, g(5/2,3/2).
