For this case, the first thing we must do is define variables.
We have then:
x: number of minutes
y: final temperature
We write then the equation that models the problem:

For y = 20 we have:

Clearing x:

Answer:
L = 3√5
Step-by-step explanation:
A square and a rectangle have equal areas.
Area of a square = Area of a rectangle
L² = H * W
If the dimensions of the rectangle are 15 units by 3 units,
L² = 15 * 3
L² = 45
Determine the length of the side of the square.
L = √45
L = 3√5
