Which expressions are equivalent to -56z+28? a) 1/2 ⋅ ( -28z + 14 ) b) ( -1.4z + 0.7 )x 40 c) (14−7z )⋅(−4) d) (8z−4)(−7) e) −2(−28z−14) !

The answers that are correct as b, c, and d

Step-by-step explanation:

In order to find this, simply perform the indicated operation.

b) ( -1.4z + 0.7 )x 40 = -56z + 28

c) (14−7z )⋅(−4) = -56z + 28

d) (8z−4)(−7) = -56z + 28

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.
