If you would like to find the rational roots of x^4 + 8 * x^3 + 7 * x^2 - 40 * x - 60 = 0, you can do this using the following steps:
x^4 + 8 * x^3 + 7 * x^2 - 40 * x - 60 = 0
(x^2 - 5) * (x^2 + 8 * x + 12) = 0
(x^2 - 5) * (x + 6) * (x + 2) = 0
1. x = - sqrt(5)
2. x = sqrt(5)
3. x = - 6
4. x = - 2
The correct result would be -6 and -2.

Answer:
- 76.71 quarts of sparkling water
- 23.29 quarts of grape juice
Step-by-step explanation:
The ratio of sparkling water to total volume is ...
water : juice = 112 : 34
water : total volume = water : (water +juice) = 112 : (112 +34) = 112/146
Then the amount of 100 quarts of sparkling grape juice that is sparkling water will be ...
water/total = w/100 = 112/146
w = 100(112/146) ≈ 76.71 . . . . quarts of sparkling water
j = 100 -w = 23.29 . . . . . . . . . quarts of grape juice
A. 1/6, 6 possible outcomes with 1 desired result.
B.67/450 will give you the answer of 14.888...% I'm going to assume your teacher will let you round to 15 so the chances are 15/100 and in simplest form is 3/20.
You will divide 50 by 10 to get 5. Then multiply 5 by 50 to get 250
