A stone is launched into the air from a height of 240 feet. The height, h, of the stone, in feet, 1 seconds after launch is given by the formula h = - 168 + 32+ + 240. After how long will the stone hit the ground?

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.

step-by-step explanation:
