How do i see if 5 + 3 x -2 and x + 2 (x + 1) + 1 are equivalent or not?

Simplify both of the expressions and see if they are the same

5+3x-2

=3+3x

x+2(x+1)

=x+2x+2

=2+3x

They are not equivalent.

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.  

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
