Answer:

Step-by-step explanation:
We have been given that the area
(in square meters) of a circular algae colony with radius r meters is given by
. The radius
(in meters) after t minutes is given by
. We are asked to write the formula for the area
(in square meters) of the algae colony after t minutes.
This problem is based on composite functions, in which function
represents radius of circle after t minutes.
To write the formula for the area
(in square meters) of the algae colony after t minutes, we need to substitute
in area formula
.

Therefore, our required formula would be
.

your answer should be 1/3 if I did my math right
The numbers aren't accurate, they dont add up
14x - (2x - y) - y
14x + (-1(2x - y)) - y
14x + (-1(2x) - 1(-y)) - y
14x + (-2x + y) - y
14x + 1(-2x + y) - y
14x + 1(-2x) + 1(y) - y
14x - 2x + y - y
14x - 2x
12x
