Answer:
0
Step-by-step explanation:
It is been considered that Discriminant is calculated by the following formula:
D = b*b - 4 * a * c
In order to simplify the calculations we can divide all the numbers by 2 and we will have the same quadratic equation:
-x^2 -4x+4=0
and as usual quadratic equation is presented as the following:
ax^2 - bx + c = 0
so in our case a = -1; b = -4; c = 4;
Then D = -4*4 -4*(-1) * 4 = -16+16 = 0
I am not quite understanding the following phrase:
"and what does it value mean about the number about the number"
but if the question was in regards of the following number '-2x^2' so number ^2 is actually the value of power so 'x' is multiplied on it is own and this equation basically means the following:
-2x^2 = -2 * (x) * (x)

Answer:
69.5309950592 cm²
Step-by-step explanation:
<u><em>Area of Square:</em></u>
Area = 
Area = 18*18
Area = 324 square cm
<u><em>Area of circle:</em></u>
Diameter = 18 cm
Radius = 9 cm
Area = 
Area = (3.14)(9)²
Area = (3.14)(81)
Area = 254.469004941 square cm
<u><em>Area of Shaded area:</em></u>
=> Area of square - Area of circle
=> 324 - 254.469004941
=> 69.5309950592 cm²
3% is equal to .03 so .03 times $350,000 equals $10,500
