C is located at (12, -10). D is located at (-2, 18). What is the midpoint of CD?

(5,4)

Step-by-step explanation:

Let us all know that in order to find the midpoint of a segment we can use the midpoint formula

(x1+x2/2, y1+y2/2)

now let us put in the values into the formula

(-2+12/2, 18-10/2)

now lets simplify

(10/2, 8/2)

(5,4)

I hope this helped you :)

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
