A rectangular garden has a length that is 7 feet longer than its width. Let w represent the width of the garden, in feet. The entire garden is surrounded by a 2.5 foot-wide walkway. Which of the following algebraic expressions are represented by the context correctly? Part A Select all that apply. H A. Area of the garden excluding walkway = W(W + 7) B. Area of the garden including walkway = (W+ 2.5) (w+9.5) . C. Perimeter of the garden only = 4w + 14 D. Perimeter of the garden with walkway = 4w + 34 Area of the garden including walkway = (w+ 5) (w + 12) Length of the garden including walkway = W + 12

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.  

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
