Answer: according to spark notes: There can be 0, 1, or 2 solutions to a quadratic equation, depending on whether the expression inside the square root sign, (b2 - 4ac), is positive, negative, or zero. This expression has a special name: the discriminant.
In this case it is 0, not 2, which was my first and wrong answer
The picture is cut off. We can't solve :/
A 42 24÷16 =1.5 1.5×28 =42 b i think its 78.4 im not sure
The anwser is a&c they go forward and up
The answer is 48.66, as the hundreth place is the 5, but you must round it up to a 6 since the 7 is larger than 5
