Answer:
Step-by-step explanation:
One way to determine if the equation has any real solutions is to look at its discriminant. For the equation ax²+bx+c = 0, the discriminant is ...
d = b² -4ac
When the discriminant is negative, both solutions to the quadratic are complex. There are no real solutions in that case.
We can find the discriminant values to be ...
A: d = 2² -4(1)(4) = -12 . . . . no real zeros
B: d = 0² -4(3)(-5) = 60 . . . two real zeros
C: d = 8² -4(-2)(0) = 64 . . . two real zeros
D: d = 10² -4(1)(26) = -4 . . .no real zeros
Expressions A and D have no real zeros.

<em>Comment on the question</em>
You are given an <em>expression</em>, not an <em>equation</em>. There is no equal sign. Hence, we cannot talk about <em>solutions</em>. We can only talk about <em>zeros</em>, values of x that make the expression have a value of zero.

Answer:
Step-by-step explanation:
I don't exactly know what the problem is asking.
4+3+2=9
Sooo, there are 9 different songs.
You then have to divide 360 by 9 to figure out how many times each song is going to play.
360/9= 40
Each song is going to play 40 times.
I hope that's the answer to the question. If it isn't, this will probably get you closer to the answer.
Good luck! :D
Speed =distance/ time taken =100/0.4 =250 miles/ hour
