Hello!</h2>
The answer is:
- The first operation match with the polynomial:
B.
- The second operation match with the polynomial:
A.
- The third operation match with the polynomial:
C.
<h2>Why?</h2>
In order to solve the given operations, we need to group the like terms.
Remember, like terms are terms that share the same variable and the same exponent.
For example:
We only operate with the variables that shares the same exponent.
Also, we need to remember the distributive property:
So, we are given the following polynomials:
And we need to perform the following operations:
First operation,
So, the first operation match with the polynomial:
B.
Second operation,
So, the second operation match with the polynomial:
A.
Third operation,
So, the second operation match with the polynomial:
C.
Have a nice day!

Answer:
It'll take 6.97 minutes to have only 1 package remaining.
Step-by-step explanation:
This problem can be interpreted as a compounded interest problem, where the initial amount is 172 packages the interest is 52% and the final amount is 1 package. The formula for compounded interest is:
M = C*(1 - r)^(t)
Where M is the final amount, C is the initial amount, r is the interest rate and t is time elapsed. So we have:
1 = 172*(1 - 0.52)^(t)
1 = 172*(0.48)^t
1/172 = 0.48^t
0.48^t = 0.006
log(0.48^t) = log(0.006)
t*log(0.48) = log(0.006)
-0.734*t = -5.116
t = 6.97
It'll take 6.97 minutes to have only 1 package remaining.
