A rectangular painting's width is 6 less than twice its length. Given that the perimeter of the painting is 84 inches, select all statements that are true.

(i'm looking for an explanation)

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.

Solve the given system of equations. 2y= -x+9 , 3x-6= -15
