1. 28
2. 2 7/12 or approximately 2.58
3. I believe 580 but I could be wrong.

The answer is just 31 + 31 + 25 + 25 = 112.
This is because you can rearrange the lines to make it a rectangle of the same size.
(2n-4)-(4n-3)
=2n-4-4n+3
=-2n-1
=-(2n+1)
Answer:
(1,1)
Step-by-step explanation:
5x-2y=1
2x+y=4
Im gonna use substitution but you could also use elimination
2x+y=4
-2x -2x
y=-2x+4
replace y in the first equation with the second equation
5x-2(-2x+4)=1
distribute -2
5x+4x-8=1
add
9x-8=1
+8 +8
9x=9
divide both sides by 9
x=1
then put x in for the equation fo your choice im gonna use the second one
2(1)+y=4
2+y=4
-2 -2
y=1
Hope this helps :))
