Answer:
-23
Step-by-step explanation:
A quadratic equation is given to us and we are interested in finding the discriminant of the quadratic equation . As we know that ,
If the quadratic equation is in Standard form ,
The discriminant is ,
The given quadratic equation is ,
On comparing it with the Standard form , we have ,
So that ,
Also note that if D < 0 , then the roots are complex conjugates .
<h3>Hence the discriminant is (-23).</h3>

Answer:
Length of the rectangle is 18 ft when its width is 4ft
Step-by-step explanation:
Let us assume that the length is represented by l.
Let us assume that the width is represented by w.
As given
The length of the rectangle varies inversely with its width.
Thus
L x 1/w
l=k/w
Where k is the constant of proportionality .
As given
If the
length of the rectangle is 6 feet when the width is 12 feet,
l=6, w=12
putting the values in l = k/w
6 = k/12
k = 12 x 6
k=72
As given
width is 4ft
k= 72, w = 4
Putting the values in, L = k/w
L= 72/4
L=18 ft
Therefore the length of the rectangle is 18 ft when its width is 4ft
Hope this helps You
