Answer: The first term is 
Step-by-step explanation:
1. To rewrite the given polynomial in descending order, you must see the exponent of each variable of the terms. Then, you must arrange the terms from bigger to smaller.
2. Keeping this on mind, you have:

3. As you can see, the first term is: 
Use the formula,
I = Prt
P = Principal amount = 400
I = interest = 18
r = annual rate
t = time in years = 9/12 = 3/4
so,
18 = 400*r*3/4
r = 0.06
so the annual interest rate is 0.06 or 6%.
