Two vertices of a polygon are (7, −18) and (7, 18) . what is the length of this side of the polygon? enter your answer in the box. units

Find the sum of 4x^{2} -4+6 and -7^{2} +3x+1

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.
