Answer:
Trinomial.
Step-by-step explanation:
Note how much terms there are in the given expressions:
Term 1: 
Term 2: 
Term 3: 
Note each meaning of the terms:
Monomial: Having only one term.
Binomial: Having two terms.
Trinomial: Having three terms.
Polynomial: Typically used to describe expressions with 4 or more terms.
In this case, there are only 3 terms, and so your answer is Trinomial.

Answer:
t = 2.52 seconds
Step-by-step explanation:
h=139-15t-16t^2
We want to know when the ball hits the ground
That would be when h=0
0 = 139-15t-16t^2
We can use the quadratic formula to find t
t = -b ± sqrt(b^2-4ac)
----------------------
2a
where a = -16 b = -15 and c = 139
t = -(-15) ± sqrt((-15)^2-4(-16)139)
----------------------
2(-16)
t = (15) ± sqrt(225+8896)
----------------------
-32
t = (15) ± sqrt(9121)
----------------------
-32
t = 15+ sqrt(9121) t = 15- sqrt(9121)
-------------------- or -------------------
-32 -32
-3.453247707 or 2.515747707
Since time cannot be negative
2.515747707
Round to the nearest hundredth
t = 2.52 seconds

First make an equation then solve for the variable.
8,800 is the end goal so that is what it is going to equal
Since his parents are contribuating 6,000 we can add that as a constant
Now it says in 2 years but it askes us in months so we times 2 by 12 to get 24 months he will be saving.
Now it is asking us how much he should save per month be we don't know that so that is our variable.
8,800 = 24x + 6,000
Solve
8,800 - 6,000 = 24x
2800/24 = x
116.67 = x (rounded for currency)
Sean would have to save $116.67 a month in order to pay for the community college
