Pls help due in 30 min USING ALGEBRA TILES Write the sum of the two algebraic expressions modeled by the algebra tiles. Let x be the variable. Then use the algebra tiles to simplify the expression.

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.  

x-3y=4

step-by-step e

10+4√2 is the answer. i dont have the time to explain.
