Answer:
The value of c that completes the square
is 1
Step-by-step explanation:
We need to find the value of c that completes the square 
The formula used will be: 
In the question given the value c can be found by breaking the middle term. we are given 2x while the general formula is 2ab for middle term so,
2(x)(1) = 2x
so, c= 1
Solving:

So, the value of c that completes the square
is 1
The given population models for the trees is given as:

It is required to find which forest will have a greater number of trees after 20 years and by how many.
To do this substitute t=20 in the equations of the models:


Hence, forest A has a greater number of trees after 20 years.
Calculate the difference:

It follows that forest A has a greater number of trees than forest B by 43 trees.
After 20 years, forest A has a greater number of trees than forest B by 43 trees.
