Answer:
These two points are 3 Units away from each other. 5 - 2 = 3
This accounts for one side of the square, to find the entire perimeter multiply 3 × 4 = 12
The perimeter of the square is 12 units
3y = 2x + 6
x + y = 7
y = 7 - x
3(7 - x) = 2x + 6
21 - 3x = 2x + 6
21 - 6 = 2x + 3x
15 = 5x
15/5 = x
3 = x
x + y = 7
3 + y = 7
y = 7 - 3
y = 4
Solution is (3,4)
The final price of the item is $22,644
The initial discount of 10% leaves the price at 90% of the retail value:

cross multiply to solve for x:
100x = 3,060,000
x = 30,600
This new price is then discounted 26%, which means the final price is 74% of $30,600:

cross multiply to solve for x:
100x = 2,264,400
x = 22,644
