What is the equation of a circle with a center at (-4, 0)
that passes through the point (-2, 1)?

x^2 + (y + 4)2 =
(x-1)^2 + (y + 2)2 =

(x + 4)^2 + y^2 =

(x + 2)^2 + (y - 1)^2 =

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
