The length of a rectangle is
2
meters more than
2
times the width. if the area is
40
square meters, find the width and the length.

Step-by-step explanation:

From the problem statement, we can set up the following two equations:

Plugging the first equation into the second, we can solve for :

Since the length must be a positive number, then we know that . We can now plug this number into the second equation to get :

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
