Answer: B
<u>Step-by-step explanation:</u>
x³ - 3x² + 16x - 48 = 0
→ x²(x - 3) + 16(x - 3) = 0
→ (x² + 16) (x - 3) = 0
→ (x² - (-16)) (x - 3) = 0
→ (x - 4i)(x + 4i)(x - 3) = 0
→ x - 4i = 0 x + 4i = 0 x - 3 = 0
→ x = 4i x = -4i x = 3

Answer:
The total distance covered in 1 hour is 4000 meters.
Step-by-step explanation:
The distance Ami'yan runs is 15 minutes = 1 kilometer
Using the unit formula,
The distance ran in 1 minute = 
Now, 1 hour = 60 minutes
⇒The distance covered in 60 minutes = 60 x (Distance run in 1 minute)
= 
So, the distance covered in 1 hour = 4 kilometer
1 kilometer = 1000 meters
⇒ 4 km = 4 x 1000 meters = 4000 m
Hence, the total distance covered in 1 hour = 4000 meters.
Another way to write this is:
x = 23y + 5
xy = 6732
Now plug in the first equation into the second:
(23y + 5)y = 6732
23y^2 + 5y - 6732 = 0
Either use quadratic equation or factor:
(y - 17)(23y + 396) = 0
y = 17 or -396/23
You know you can automatically eliminate the second y because it's negative and you need the two integers to multiply to a positive number (6732).
Plug y = 17 back into either equation (second might be easier):
17x = 6732
x = 396
