Write the equation for the circle in standard form
x2 + y2 - 12x - 12y + 36 = 0

Let w=23 . what is the value of w + 45 ?

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

Two cyclists 84 miles apart start riding toward each other at the samen time. one cycles 2 times as fast as the other. if they meet 4 hours later what is the speed (in miles) of the faster cyclists
