The perimeter of a shape is the sum of its side lengths
The expressions for the perimeter of the frame are 4(l + 2) and 4l + 8
<h3>How to determine the perimeter of the shape</h3>
The side length of the frame is given as l
So, the perimeter of the frame is
:
When 2 inches are added to each length, the perimeter of the frame becomes

Expand

Hence, the expressions for the perimeter of the frame are 4(l + 2) and 4l + 8

Midpoint of (a,b,c) and (e,f,g) is
((a+e)/2,(b+f)/2,(c+g)/2)
just average them
the x value
(2+-2)/2=0/2=0
the y value
(-2+0)/2=-2/2=-1
the z value
(4+6)/2=10/2=5
(0,-1,5) is da midopint
Multiply straight across
5/1 * 3/4 = 15/4
now change it into a mixed number
3 3/4
Divide 141 by 73
73 only goes into 141 once
