How to solve this w2-64= by facturing

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.

When 142 is added to a number the result is 64 more times the number my options are 35 37 39 41

Is the power produced directly proportional to the wind speed, give reasons for your answer?
