Answer:
Step-by-step explanation:
The discriminant is found in
which is part of the quadratic formula. In
, a = 4, b = 10, c = -16. Filling in for the discriminant:

It's positive so we know we have real roots; it's not a perfect square, so our solutions are 2 complex rational.
In
, a = -16, b = -7, c = 3. Filling in for the discriminant:

It's positive and not a perfect square so the 2 solutions are complex rational

Answer:
10.5 miles.
Step-by-step explanation:
If she walks 7/10 of a mile each morning, and 1, 4/10 of a mile each day, Belle walks a total of 2 1/10 of a mile each day (2.1) miles each day)
We can just multiply the amount of miles per day by 5, (2.1 x 5) and we get 10.5 miles total.
1/36+1/36=2/36. why? because their are 6 sides. you must multiply. and for each dice ylu have a possibilty of 1/36.
