Looks as tho' you may have omitted x^2 by mistake.
If you started out with 0 = 4 - 7x + x^2, then 1x^2 - 7x + 4 = 0.
The coefficients are then {1, -7, 4}. The constant term is 4.
well #7 is a solution.
y= 9x (4,36)
9 times 4 = 36
36/9=4
so the ordered pair is a solution.
y=3x-5 (7,16)
3 times 7 -5= 16
so once again the ordered pair is a solution.
Hoped this helped.

Step-by-step explanation:
The answer is Rey who has 20 has led
If the radius of the circle is 1, its area is π*1^2 = π units^2.
If the radius of the circle is 1, the side length of the square is √2 and its area is (√2)^2 = 2.
The ratio of square area to circle area is 2/π ≈ 63.7%.
