Theo started to solve the quadratic equation (x + 2)2 – 9 = –5. he added 9 to both sides and the resulting equation was
(x + 2)2 = 4. next, he took the square root of each side.

which was the resulting equation of that step?

Graph this piece wise function on the coordinates grid.

Triangle jkl is transformed to create triangle j'k'l'. the angles in both triangles are shown. j = 90° j' = 90° k = 65° k' = 65° l = 25° l' = 25° which statement is true about this transformation? it is a rigid transformation because the pre-image and image have the same corresponding angle measures. it is not a rigid transformation because the corresponding side lengths are not equal. it can be a rigid or a nonrigid transformation depending on whether the corresponding side lengths have the same measures. it can be a rigid or a nonrigid transformation because a pair of corresponding angles measures 90°.
