PLEASE HELP WILL GIVE BRAINLIEST!! If K is the midpoint of JL, JK=9x-1, and KL=2x+27, find JL. A. 35
B. 70
C. 62
D. 48

A, 35

Step-by-step explanation:

9x - 1 = 2x + 27

7x - 1 = 27

7x = 28

7x/7 = 28/7

x = 4

and now we plug it in,

9x - 1

9(4) - 1

36 - 1

35

and for the second point,

2x+27

2(4)+27

8+27

35

Hope this helps. Sorry this is a late response.

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

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.
