Greetings!
A Monomial only contains one term, hence the its spelling: <em>Mono </em>meaning one.
Therefore, none of the example you gave are monomials.
They are examples of trinomials. (three terms)
Hope this helps.

Answer:
DNE
Step-by-step explanation:
Given that two particles travel along the space curves

To find the points of intersection:
At points of intersection both coordinates should be equal.
i.e. r1 =r2
Equate corresponding coordinates

I equation gives t =-1
Substitute in II equation to get 
i.e. t cannot be real
Hence no point of intersection

Answer:
1.25 hours
Step-by-step explanation:
If you're going 60 miles per hour, that's exactly how much miles you travel in an hour if that is your constant speed you are going the entire time, so it is at least 1 hour and we know it's not 4500 hours and it cant be .8 hours or 135 hours, think of yourself going on a caride would it really take 135 hours ? No so its 1.25. Also multiply 60 by 1.25 and you get 75.
