Alina is an ecologist who studies the change in the bear population of Siberia over time. The relationship between the elapsed time, t, in years, since Alina began studying the population, and the total
number of bears, N(t), is modeled by the following function:
N(t) = 2187 - (0.67)

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125
