A bus travels through the city and stops every mile. The first stop on the route is the 8th Avenue Coffee Shop, which is located
15 blocks east and 22 blocks north of the central station. The last stop on the route is the airport, which is located 25 blocks west and 36 blocks south of the central station. A student calculated the middle stop along the bus route to be located 20 blocks east and 29 blocks north of the central station. Evaluate the student’s answer. A.
The answer is correct.
B.
The answer is not correct. The student averaged a horizontal movement with a vertical movement.
C.
The answer is not correct. The student did not compute the sums of the horizontal and vertical directions correctly.
D.
The answer is not correct. The student did not average the distances.
So for this you need the two solutions to be x= -9 and x=3 then move over the numbers and put in brackets (x+9)(x-3) then multiply together x^2+9x-3x-27 then combine like terms to get x^2+6-27
