B is the midpoint of AC. If AB = 2 + 5 and BC = 2x – 11. Find the measure of AB

If 1/2 is half of 1, what is 1/2 of 2,3, and 4?

This is so harddd! solve. 1 + 1 = solve 4 + 4 = solve 3 x 3

Aball is thrown from a height of 139 feet with an initial downward velocity of 15 ft/s. the ball's height h (in feet) after t seconds is given by the following. h=139-15t-16t^2 how long after the ball is thrown does it hit the ground? round your answer(s) to the nearest hundredth. (if there is more than one answer, use the "or" button.) t =
