Using the following equation, find the center and radius of the circle.
x^2 + 4x + y^2 − 6y = −4
step 1: (original equation) x^2 + 4x + y^2 − 6y = −4
step 2: (group the like terms)
step 3: (complete the quadratics)
step 4: (simplify the equation)
step 5: (factor each quadratic)
step 6: (identify the center and radius)

can someone complete these steps in order

Alake near the arctic circle is covered by a 222-meter-thick sheet of ice during the cold winter months. when spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. after 333 weeks, the sheet is only 1.251.251, point, 25 meters thick. let s(t)s(t)s, left parenthesis, t, right parenthesis denote the ice sheet's thickness sss (measured in meters) as a function of time ttt (measured in weeks).
