The perimeter of a triangle is 54 in. The shortest side is 11 in. less than the longest side. The middle side is 20 in. less than the combined lengths of the shortest and longest sides. Find the lengths of the three sides.

b

step-by-step explanation:

if a was wrong then it has to be b it cant be c either because not all the y intercepts are the same!

ok now , i would like brainlest plz

the two may have that, even a breakdown is probably offered

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.
