A car travels at an average speed of 60 km/h for 2.1 hours.
How far did the car travel in km

Monica build a remote control toy airplane for science project to test the plane she launched it from the top of a building the plane travel a horizontal distance of 50 feet before landing on the ground a quadratic function which models the height of the plane in feet relative to the ground at a horizontal distance of x feet from the building is shown

The angles below are supplementary. what is the value of x? a pair of supplementary angles is shown. one angle measures 7x + 33, and the other angle measures 70. 5.3 8.14 11 14.7

Consider the proof. given: segment ab is parallel to line de. prove: what is the missing statement in step 5?
