Identify each equation as an identity, a contradiction or neither

1. 6x + 4x - 6 = 24 + 9x

2. 25 - 4x = 15 - 3x + 10 - x

3. 4x + 8 = 2x + 7 + 2x - 20

Crickets can jump with a vertical velocity of up to 14 ft/s. which equation models the height of such a jump, in feet, after t seconds? h(t) = –16t2 + v0t + h0 h(t) = –16t2 + v0t + 14 h(t) = –16t2 + 14t h(t) = –16t2 + 14t + 14 what is the maximum height the cricket reaches? round to the nearest thousandth. h = feet
