Question 1 1 pts
Fill in the missing terms to create an equivalent expression for each polynomial.
Use numbers, variable letters, and symbols only. Do not use spaces or words.
4x - 7 = 4x +
6x2 - 8x --9 = 6x2 +

16 more than the product of 5 and p

Write an expression that has three terms and simplifies to 4x - 7. identify the coefficient(s) and constant(s) in your expression

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 =
