To determine the coordinates of the midpoints of a line segment, get the average of the both the abscissas and ordinates. In this example, the average of the abscissas is 22 and that of the ordinates is -4. Thus, the midpoint is (22, -4).
I got b
for my
answer ok ??????????????????????
To solve this problem first find the perimeter of the rectangle by using the formula P= 2(L+W).
Plug in your number and you get the number 28.
Now, because Noah is putting in a post at every yard and our answer is already in yards we are done.
Noah will need 28 post to build the dog run.
P=2(8+6)
P=2(14)
P=28
Hope this helps :-)
