Hello from MrBillDoesMath!
Answer: A, C, D
Discussion:
The solution of the quadratic equation ax^2 + bx + c = 0 is
x = ( -b +\- (b^2 - 4ac) ^ (1/2) ) /2a
The expression b^2 - 4ac is called the discriminant, occurs in the numerator of the solution, and also occurs inside a square root (called a radicand).
The question, while intelligible, should be stated more clearly.

31 is the answer because you would do 5 x 3 an that's 15 and if it's squared u technically add 15 a second time
Answer:
0.8
Step-by-step explanation:
Things to remember:
- You can add as many 0's on the end of a decimal and it will still equal the same number, as long as the 0's are on the right side of the decimal point. For example, 0.7 = 0.7000.
- The lowest value has the lowest probability
So, let's rewrite the options with the same amount of decimal points:
1.00
0.90
0.80
0.85
Now, find the value under 0.82. In this option, the lowest value is 0.80, and it is under 0.82, so it is the answer.
