Step-by-step explanation:
it's basically finding the area for a cube and then cutting it in half, so multiply it all together and then divide by 2. sorry if I'm wrong lol
n + 1 = 4(n - 8)
n + 1 = 4n - 32
n - 4n = -32 - 1
-3n = -33 / : (-3)
n = 11
Let's solve this using unitary method ~
Therefore , the ostrich will run 105 meters in 5 seconds.
