The length plus the width of a rectangle is 10. Let x represent the length. The equation for the area y of the rectangle is
y = x/10 - X). The y value of the vertex gives the maximum value of the area of the rectangle.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

5/12, or 5: 12

step-by-step explanation:

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.
