ax^2 +bx+c=0
X^2 + 2x+8=0 so a=1, b=2, c=8
Discriminat= b^2 -4ac=2^2 -4•1•8=4-32=-28
So there are no real number solutions, yet there are complex numbers solutions.
Solutions=(-b+- sqrt (discriminant))/2•a
=(-2+-i sqrt ( 2•2•7))/2
Solutia 1= -1 + i sqrt7
Solutia 2= -1 - i sqrt 7
The answer is 10............
Well, one divides by 7, actually, because the total number of tickets is 6+1 times the # of discount tickets. That is, 1,456/7. You don't need to actually perform this division.
Answer: Caroline = 225
Step-by-step explanation:
Let Sarah be x
Caroline will be 3x
Bridget will be 2(3x) = 6x
x + 3x + 6x = 750
10x = 750
x = 750 / 10 = 75
Caroline gets 3x = 3 * 75 = 225
