Answer:
okay so you have to take the steps you learned in math and apply because this is actually hard and you just have to really take your time and annotate the exerpt
Step-by-step explanation:
Answer:
The sprinter
Step-by-step explanation:
Change cyclist to same units as sprinter (m/s)
20 km = 20x1000 m = 20000 m
1 hour = 60 minutes = 60 x 60 = 3600 sec
So 20 km/hr = 20,000 m / 3600 sec = 5.6 m/s
The sprinter is faster as he travels at 8 m/s.
(Similarly if you change the sprinter's speed into km/hr
you should get 28.8 km/hr)
X = 21
Y = 20
Because:
SR is congruent to ML
Answer:
3x^2-5x-2
Step-by-step explanation:
(9x^3-18x^2-x+2)÷(3x-1)
[9x^2(x-2)-(x-2)]÷(3x-1)
[(x-2)×(9x^2-1)]÷(3x-1)
(x-2)×(3x-1)×(3x+1)÷(3x-1)
(x-2)×(3x+1)
3x^2-x-6x-2
3x^2-5x-2
