Which best describes the rule for this pattern? 1,-12,12,-1

Let w=23 . what is the value of w + 45 ?

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

Match the equivalent expressions. x - 3y + 12 12 - 3y - 2x + x + 2x 3x + 2y - 2x + y + 12 3y + 12 3x + y - 12 4y + 3y + 3x - 6y - 10 - 2 x + 3y + 2x - 3x + 7 + 5 x + 3y + 12 5 + 2y + 7x - 4x + 3y - 17
