A rancher has a square cow pen with side length x. He deicdes to change the shape of the pen while still using
the same amount of fencing materials. The equation
(x + 10)(x - 10) = 300 represents the relationship
of the new side lengths (in feet) of the pen and its area
(in square feet).
a. If 300 represents the area of the new cow pen, what
do the expressions (r + 10) and (x - 10) each
represent?

Teams of 4 are competing in a 1/4 mile relay race. each runner must run the same exact distance. what is the distance each teammate runs?

Drag the tiles to the correct boxes to complete the pairs. match the exponential functions with their horizontal asymptotes and y-intercepts. f(x) = 7x − 4 f(x) = 3x+2 + 4 f(x) = 9x+1 − 4 f(x) = 2x + 4 horizontal asymptote and y-intercept exponential function horizontal asymptote: y = 4 y-intercept: (0, 5) arrowboth horizontal asymptote: y = -4 y-intercept: (0, 5) arrowboth horizontal asymptote: y = -4 y-intercept: (0, -3) arrowboth horizontal asymptote: y = 4 y-intercept: (0, 13) arrowboth
