A rectangle's width is double its length. If the perimeter is 78 feet, what is the length and
width ?

Triangle xyz with vertices x(0, 0), y(0, –2), and z(–2, –2) is rotated to create the image triangle x'(0, 0), y'(2, 0), and z'(2, –2). which rules could describe the rotation? check all that apply. r0, 90° r0, 180° r0, 270° (x, y) → (–y, x) (x, y) → (y, –x)
