A20-a18=a1+19d-a1-17d=2d =281-97
so
d=92
This is fairly simple. Divide 2,871,000 by 10 and that's your answer!

Also, since you're dividing by a factor of 10 (or in this case, <em>10</em>) you can just take away as many places as are zeros in the number you're dividing from. This works for <em>10, 100, 1,000, 10,000, etc. </em>In this case, since there is only one zero in 10 you only take away one place marking, which gives you 287,100.
Answer: 3y3+7y2+−4y+3
Step-by-step explanation:
3y2+y3+−5+4y2+−4y+2y3+8
Combine Like Terms:
=3y2+y3+−5+4y2+−4y+2y3+8
=(y3+2y3)+(3y2+4y2)+(−4y)+(−5+8)
=3y3+7y2+−4y+3
