Help me please, I've been stuck for a hot minute

b. 5z-10 = 5(z-2)    c. c-2c^2= c(1-2c)    d. r+r+r+r= r(1+1+1+1)= 4r   e. 2x-(1/2) = (1/2)(4x-1)

Explanation:

you just need to find a common factor that you can divide out  of each term. ex. with the 5z-10 both 5z and 10 are divisible by 5, so you can factor that out. to check the answers just multiply it. if you still don't get it, look up "factoring binomials"

2x3 – 6x2 – 14x + 24 square centimeters

if i'm wrong i'm sorry : )

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.
