Consider the steps for solving 3x^2 - 42x 9 = -5 step 1: 3x^2 - 42x = -14 step 2: 3(x^2-14x) = -14 step 3: 3(x^2- 14x 49) = -14 number should be added to the right side of the equation?

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.
