Answer:
Discriminant = 49, two real solutions
Step-by-step explanation:
Discriminant = b² - 4ac = (5)² - 4(3)(-2) = 25 + 24 = 49
Since 49>0, then the quadratic equation has two real solutions.

1. find the area of the rectangle
2. find the area of the triangle
3. add the areas for the total area
1. area of a rectangle = lw = 8x4 = 32cm
2. area of triangle = 1/2bh
the height is the line drawn from the vertex A to the center of side BE
the base is 1/2 the length of side BE therefore base = 4
because the hypotenuse is 5 and the height is 4 the laws of the pythagorean theorem state that the base equals 3 (3-4-5 right triangle)
Therefore the area = 1/2(3)(4)= 1/2(12) =6cm
3. The total area equals 32cm + 6cm =38cm
To find arc length, start by dividing the arc's central angle in degrees by 360. Then, multiply that number by the radius of the circle. Finally, multiply that number by 2 × pi to find the arc length.
