If you finish the question I may be able to answer it. ^^
For this case we have the following polynomial:

We must find the greatest common factor of the terms of the polynomial.
The GCF of the coefficients is given by:

Then we look for the GFC of the variables:
We have then:

Finally rewriting we have:

Answer:
the complete factored form of the polynomial is:

A blank root or a root of blank
Answer:
An exponent value in a would make the system inconsistent because it will either gain or lose height over time.
Any real number without an exponent value will make the system consitent.
Any infintite/repeating number will make the system both consistent and inconsistent. it is consisent because it will stay at a constant rate but also inconsistent because it is repeating and will never end.
Answer:
distance = rate x time
3 and 1/5 = 3.2 and 3 and 3/5 = 3.6
distance = 3.2 x 4.5 = 14.4
14.4 = 3.6 x T
T = 14.4 / 3.6 = 4 <--- Pedro's time
