Check the picture below.
so notice, their perimeter is the same, because the perimeter is just one rod anyway, and all rods are the same length, thus
To complete the square, the second degree term must have a coefficient of 1.
Since the second degree term here has a coefficient of 4, we start by dividing each term on both sides by 4.
Now we can complete the square.
First, we need to find what number completes the square.
We take the coefficient of the first degree term, -7 in this case.
Divide it by 2 and square it. -7 divided by 2 is the fraction -7/2.
Now we square -7/2 to get 49/4.
We add 49/4 to both sides.
(7+2-3-8)=0
N=7

Hope this helps
1) Reflecting over y=x means 
. So, the coordinates of the image are:
2) Rotating 90 degrees counterclockwise about the origin means 
, so the vertices of the image are:
3) The vertices of the image are:
For the top left box you T to get to W is 3 so for R it would bevy because that would be ahead 3 for E you would go back 3 so it would be B. A is D. The rule is probably add 3. The top right is basically the opposite so Hot-cold, left-right, first-LAST, soft-hard, and top-BOTTOM. The rule is probably the opposite . The bottom one is adding 3 just like the top left. Hope you understand this I know it's a lot of writing.
