The midpoint pf ab is m ( 0,-1) . if the coordinates of a are (4,3), what are the coordinates of b

The coordinate of point B is (-4, -5).

Step-by-step explanation:

Given:

M is the midpoint of a AB

let

To Find:

Solution:

As M is the midpoint of so applying midpoint formula we have

X coordinate i.e x and Y coordinate i.e y given by

On substituting the values for X1, X2, X and Y we will get

So the coordinates for B (x2,y2) is B (-4,-5).

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
