There are 88 marbles in a bin and 25 percent of the marbles are red how many red marbles are in the bin ?

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.

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)
