Answer:
B. Division
You cannot add anything when you divide, so it would remain a polynomial.
Answer:
4 km per hour and 6 km per hour.
Step-by-step explanation:
The combined running rate = 30/3 = 10 km/h.
If one runner's speed = x then the other one's speed is x+2 km/h.
So x + x + 2 = 10
2x = 8
x = 4
So one runs at 4 km/h and the other at 6 km/h.
The coefficient is the number . so if the problem said 16x the coefficient would be 16 . the answer is 14
