The length of a rectangle is 9 yd more than twice the width x. The area is 455 yd?. Write an equation in terms of x that represents the given relationship.

x * (2x + 9) = 455

Step-by-step explanation:

To express the width in terms of x, given information

x = width

The given information says the length is 9 more than 2 times the width. Length can be expressed in terms of x like this.

2x + 9 = length

The area of a rectangle is length x width, and the given area is 455.

x * (2x + 9) = 455 or 2x^2 + 9x = 455

the answer is 375 miles

step-by-step explanation:

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.
