Step-by-step explanation:
Airport: 2 feet per second.
Total distance 152 ft in the same amount of time it takes him to talk 72 feet on the pavement.
152/2 = 76 - This is how many seconds he was walking in the airport.
He walked 76 seconds and moved 152 feet.
So that means if the SAME time was used so 76 seconds he walked 72 feet, then we can do 72ft/76sec to get 0.94ft/sec
Yes they do. Notice that for each step in x there a +4 in y. If you want an equation we can set it up with the inforation given

Yes theres a relationship because for every meter she runs it takes her 4 minutes for each.

Answer:

Step-by-step explanation:
(5x^3+4x^2)−(6x^2−2x−9)
To find the opposite of 6x^2−2x−9 find the opposite of each term.
5x^3+4x^2−6x^2+2x+9
Combine 4x^2 and 6x^2 to get −2x^2.
5x^3-2x^2+2x+9
