Answer:
c. This quadratic equation has two complex solutions.
Step-by-step explanation:
Of the choices ...
a. This quadratic equation has exactly one real solution.
b. This quadratic equation has two real solutions.
c. This quadratic equation has two complex solutions.
d. This quadratic equation has no solutions.
The one that is true is <em>c: two complex solutions</em>.
__
The discriminant of quadratic ax^2 +bx +c = 0 is ...
d = b^2 -4ac
For this quadratic, the value is 6^2 -4·5·2 = -4.
When the discriminant is positive, there are two distinct real solutions.
When the discriminant is zero, there is one real solution.
When the discriminant is negative, there are two complex solutions. The discriminant of this quadratic is negative, so there are two complex solutions.

Answer:
area= 41 cm^2
Step-by-step explanation:
area=5 x 8.2 = 41 cm^2
divide the rhombus in half either way and you have two identical triangles.
area of triangle =0.5 x base x height
double that for the two triangles and you have the area of the rhombus.
Answer:
y = -2x - 2
Step-by-step explanation:
y = Mx + c
4 = -2(-3)+ c
4 =6+ c
c = -2
Answer:
So, C, and D.. can easily be marked incorrect. This is because in the question it asks, "Atleast 16" This leaves us with answer choice A and B. Answer choice (A), is a closed circle, while answer choice (B) is an open circle.
Closed circles include the number at the end point (less than/greater than/equal to), and open circles do not (less than greater than).
answer choice A. Closed circle, shifting to the right.
