Asap! 20 points! i have to pass math! from the equation, what is the value of the radius, r? x^2 + y^2 = 144 asap

For the given quadratic equation convert into vertex form, find the vertex and find the value for x=6 y=-2x^2+2x+2

Can somebody me out with this question

Two rigid transformations are used to map abc to qrs. the first is a translation of vertex b to vertex r. what is the second transformation? a reflection across the line containing ab a rotation about point b a reflection across the line containing cb a rotation about point c
