Answer:
a
Step-by-step explanation:
Answer:
a) The discriminant of the equation = - 44
b)The nature of the roots will be imaginary.
c)
Step-by-step explanation:
Here, the given expression is
or,
Now the discriminant (D) of a quadratic equation
D =
Hence, the discriminant of the equation = - 44
As D< 0, so the roots will be imaginary.
Now,by quadratic formula :
So, here
So, either
or,
Answer:
Stephen has 9 trees
Alice has 21 trees
Step-by-step explanation:
<u>At the beginning:</u>
Stephen = x trees
Alice = x + 12 trees
<u>At the end:</u>
Alice = (x + 12) - 4 trees
Stephen = x + 10 trees
Total = 36
Then
Stephen - 9 trees
Alice - 9 + 12 = 21 trees
Answer:
9
Step-by-step explanation:
6 x
- = -
8 12
the relationship from 8 to 12 is divided by.666666666666
So, we do the same for 6
We get 9.
