Answer is A. 12c
A monomial only consists of one term (12c), 
Binomials consist of two terms (c^2 - 16)
Trinomials consist of three terms (c^2 + c + 6)
An easy way of remembering which is which is to look at the prefixes. 
Mono= 1
Bi= 2
Tri= 3

Answer:
7 Rows with one row having 6 Chairs.  The other 6 Rows will have 8 chairs each.
  6x8 = 48 chairs + 1x6 = 54 chairs.
Step-by-step explanation:
1 Row = 8 Chairs  [1Row/8Chairs]
(1Row/8Chairs)*(54Chairs) = (54/8) Rows  = 6.75 Rows
The manager needs 7 rows, one row will have only 6 chairs   [(0.75 Rows)*(8Chairs/1Row) = 6 Chairs
