The correct answer is A). None
Step-by-step explanation:
The given quadratic polynomial has 3 roots and some of roots are x= and x=6+i
It is necessary to note that one of the roots is a complex number and root of complex number always in pair of the conjugate to each other.
Since x=6+i
Conjugate of (6+i) is (6-i)
<em>Therefore, (6-i) is 3rd required root of a polynomial </em>
<em>The correct answer is A). None</em>
Answer:
72 sq. units
Step-by-step explanation:
Find the diagram attached
The rhombus is the area of the two triangles and the rectangle
Area of triangle = 1/2 * base * height
Area of triangle = 1/2 * y * h
Area of triangle = 1/2 * 3 * 8
Area of triangle = 3 * 4
Area of triangle = 12 sq.units
Area of 2 triangle = 2(12) = 24 sq. units
Area of the rectangle = length * width]
Area of the rectangle = h (x-y)
Area of the rectangle = 8(9-3)
Area of the rectangle = 8 * 6
Area of the rectangle = 48 sq. units
Area of the rhombus = 24 + 48
Area of the rhombus = 72 sq. units
