A chemist is observing a solution's temperature over a four-hour period that starts at -12.4°C. In the four hours, the temperature rises 5.7°C and drops 8.1°C. What is the temperature of the solution after four hours?​

Which is an equation for the nth terms of the sequence 12,15,18,21

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.

Can you me find the missing length. i attached an image.
