Answer:

Step-by-step explanation:
The quadratic formula is:

The discriminant of a quadratic is just the expression under the square root, or
. This can tell us the number of solutions a quadratic has.
If the discriminant is:
- Positive = 2 real solutions
- Equal to Zero = 1 real double/repeated solution
- Negative = 0 real solutions, but 2 imaginary solutions
Our quadratic equation has a discriminant of 5, which is positive. Therefore, it has 2 real solutions.
The answer is 20.4285714285
Answer:
Uh, I'm assuming you are trying to to say how much feet there was? If not im terribly sorry, But the feet walked would of been 399 If this is not what the question was, Please ignore my comment.
Step-by-step explanation:
To get the answer You need to subtract 566 from 965 and that makes 399 or -399
4x:3x and 4x+3x=63 --> 7x=63 --> x=9, so to find the bigger number (4x) take 4*9=36
