Answer:
Here, 
, hence the quadratic equation has two distinct real roots.
Step-by-step explanation:
Given quadratic equation is 
.
Let, the quadratic equation is 
[where, 
are the constants]
The Discriminant 
Case 
: 
, if the discriminant is greater than 
, it means the quadratic equation has two real distinct roots.
Case 
: 
, if the discriminant is less than , it means the quadratic equation has no real roots.
Case 
: 
, if the discriminants is equal to , it means the quadratic equation has two real identical roots.
Now,
we have , where 
∴
Here, , hence the quadratic equation has two distinct real roots.
Answer:
C
Step-by-step explanation:
Hello!
Another way to put it would be scientific notation. to do so, you would need to get a digit 1-10 multiplied by 10 to a certain power.
For this problem, scientific notation is 1.67(10^16).
To check our answer, we will move the decimal to the right sixteen times because the exponent is positive. In other words, we will add fourteen zeros because we need two to turn 1.67 into 167. This gives us 16,700,000,000,000,000, which matches the question. (This number in word form is 16 quadrillion seven hundred trillion.)
Our final answer is 1.67(10^16).
I hope this helps!
Answer: I think the answer is 15.
Answer:
A. 4
Step-by-step explanation:
Triangle ABD = Triangle BCD
Both hypotenuse are equal in length.
x + 2 = 3x - 6
x - 3x = -6-2
-2x = -8
x = 4
