Consider all rectangles with an area of 256 cm squared. let x be the length of one side of such a rectangle. express the perimeter as a function of x and determine the dimensions of the rectangle that has the least perimeter

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.
