Step-by-step explanation:
tbh I am not sure if this is right but here
<span>x2 − 8x + 16
= (x - 4)(x - 4)
= (x - 4)^2</span>
59.952 in the nearest tenth is 60
Yes because in Mrs. Benson‘s class there are 20 students and in Mrs Tracy’s class there are only 18
Let the distance be x miles
Time = Distance / speed
Time taken by Mike to go to his friend's house = x / 40 hours
Time taken by him to return = x / 45 hours
Total time = x / 40 + x / 45 = 4 hours
= 9x + 8x = 1440 miles
17x = 1440
= x = 1440 ÷ 7
= x = 84.706
Time taken to return home = 84.706 /45= 1.882 hours .
Therefore , Mike took 1.882 hours to reach home .
