Please help on this i dont get it at all!

I hope this helps you out!!

We start off by drawing out the triangle on a graph! Placing points (x ,y) at

(-3, 5), (-5, -2) and (2, -2). I've included a screenshot of how the triangle should look to help you out visually!

From there, to find the area we use the equation, area = b • h.

To find the base, we subtract: -5 - 2 = -7, meaning that the base equals 7.

And to find the height, we subtract: 5 - (-2) = 7, also meaning that the height equals 7 as well.

Plugging those two numbers in the equation for area, we get:

area = 7 • 7

area = 49

area = 24.5 or 24 1/2, in this case your answer should be B.

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.
