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.
We want to study a general product, and find information about the ones place.
We will see that the ones place is always zero.
We have the expression:
10×?
Where ? can be any number between 1 and 9 (only whole ones)
What is true about the digit of the ones place (the first digit at the left of the decimal point) in each product?
Let's give ? some different values and see what happens:
10×1 = 10
10×2 = 20
10×3 = 30
etc...
We can see that the ones place will always be equal to zero.

When u add it stays the same but for subtraction u change the sign.
Example: 2- (-5)=7
Answer:
No she doesn't have enough paint.
Step-by-step explanation:
You have to find the area of both walls then subtract both areas by 250. It would give you a negative number, meaning there is not enough paint.
Answer:
Step-by-step explanation:
● formulas of valume = πr²h
- 22/7×12×12×38•4 ft
- 3•14×144×38•4 ft
- 452•16×38•4 ft
- 17362•944 ft³
● now nearest to the number
- 17262•944 ft³ nearest tenth is 17360ft³.
