For this case we have the following polynomials:

By subtracting both polynomials we have:

What we must do is subtract terms of the same degree.
We have then:
Answer:
will be a polynomial
Linear because there is a constant change (+3)
Answer:
The total number of trees the farmer planted = 1056 trees
Step-by-step explanation:
It is given that,
A tree farmer Planet 3 types of trees on 22 acres of land and,
he planted 48 trees per acre
<u>To find total number of plants</u>
There are 22 acres of land.
In one acre he planted 48 trees.
Therefore total number of plants in 22 acers = 22 * 48 = 1056 trees
The slope of the line is positive
