We can start with the first two sets
(x+3i)(x-3i) = x²-9i² then simplify it to x²+9
multiply the next two
(x+1)(x-1) = x²-1
then multiply those two together
(x²+9)(x²-1) = x∧4-x²+9x²-9
combine like terms x∧4+8²-9
that is your answer

Answer:
It is a trinomial.
Step-by-step explanation:
Trinomials have 3 terms connected by plus or minus signs.
The answer is y=3x.
y=21, x=7
y=mx (m is the variable for slope)
21=m(7)
m=21/7
m=3
