Answer:x^2 + 8x + 20
a = 1
b = 8
c = 20
Discriminant = b^2 - 4ac
=> 8^2 - 4(1)(20)
=> 64 - 80
=> -16
As -16<0
So, equation has no real roots

Answer: 12
Step-by-step explanation:
|-12| |?| the lines on the outside mean that the answer has to be the absolute value examples:
|-3|=3
|2|=2
|-72|=72
Common solution for each problem:
let
1st point=(x1,y1)
&,
2nd point=(x2,y2),then,
distance between 1st and 2nd point is:
√[(x2-x1)²+(y2-y1)²]
Just replace these x2,y2,x1,y1 with given points and you will get required answer..
k * 3 = s
k = Katie and s = Sarah
Although you did say expression, what I have is an equation.
