Answer:
The discriminant of f is 92, and it has no real zeros
Step-by-step explanation:
The discriminant of a quadratic is
, where the quadratic is in the form
. The discriminant of this one is therefore:

Since the square root of a negative number is imaginary, this quadratic has no real number zeros. Hope this helps!
Answer:

Answer:
3z(2x - 3)
Step-by-step explanation:
Area of a rectangle, a = height * width
height, h = 3z
width, w = 2x - 3
a = 3z * (2x -3)
expand
a = 6xz - 9z
a = 3z(2x - 3)
Answer:
m=3
b=(0,5)
Step-by-step explanation:
If you would like to solve the equation k / 2 + 9 = 30, you can calculate this using the following steps:
k / 2 + 9 = 30
k / 2 = 30 - 9
k / 2 = 21 /*2
k = 21 * 2
k = 42
The result is 42.
