If the discriminant of a quadratic equation, given by B^2-4AC is positive, it has 2 real solutions. If 0, it has 1 real solution and if negative it has 0 real solutions.
Answer:
The answer is B.
Step-by-step explanation:
Its B because the lower the altitude the higher the pressure, and in this case the air towards the ground is being moved up, which is letting cold air sink back down.
Well on this problem recall area of a rectangle is defined by:
A = lw our w = 1/6 and our l = (x +

) we have let 'x' represent our original length.


12x + 8 = 11
12x = 11 - 8
12x = 3
x =

So our original length is
Answer:
The First one: f(-2) a. 9
good luck!
