First, put your polynomial in standard form(ax²+bx+c=0). Then plug the a,b and c for x=(-b+-√b²-4ac)÷2a. As a result, you can either get one, two or no real answers.
2x + 2y = 6 . . . . . (1)
x + 3y = -1 . . . . . (2)
(1) x 3 => 6x + 6y = 18 . . . . . (3)
(2) x 2 => 2x + 6y = -2 . . . . . (4)
(3) - (4) => 4x = 20
x = 20/4 = 5
Answer:
The approximate area of the circle is 27.5184∧2
Step-by-step explanation:
In order to calculate the approximate area of the circle we would have to calculate the following formula:
approximate area of the circle=approximate area of one triangle*number of congruent sectors
number of congruent sectors=16
approximate area of one triangle=1/2*base*height
base=1.17 units
height=2.94 units
Therefore, approximate area of one triangle=1/2*1.17*2.94
approximate area of one triangle=1.7199 units∧2
Therefore, approximate area of the circle=1.7199 units∧2*16
approximate area of the circle=27.5184∧2
