d = 4 t
d + t = 20
5 t = 20
t = 4
d = 16
16-4 = 12
You could have a Quadratic with 2 distinct solution meaning you have 2 different X intercepts
2 roots means the discriminan is positive in other words
D>0
When the discriminan is 0, D=0 we have exactly one x-intercept.
Discriminan D=0
and finally, if the discriminan were negative
D=0
then there is no solution or root at all.

Step-by-step explanation:
he/ she is right that's the answer
Answer:
Step-by-step explanation:
Given that:
y = f(g(x)) = + 10
It is obviously that g(x) is put as an independent variable of f(x) to have the equation of y written above.
So
Hope it will find you well.
