Let's solve ~
Calculate discriminant :






Now, let's calculate it's roots ( x - intercepts )



So, the intercepts are :

and

Answer:
x=3
Step-by-step explanation:
You would do 238855 divided by 75 ===3184.73333 mph
7x + 18 > -3
Subtract 18 from both sides,
7x > -21
Divide from 7,
x > -3
In short, Your Answer would be Option D
Hope this helps!
