Answer:
4262
Step-by-step explanation:
2 + 7x^2- 2x^3-8x +7x^4 at x = 5
= 2 + 7*(5)^2 - 2*(5)^3-8*5 +7*(5)^4
=2+175-250-40+4375
=4552-290
=4262
The first one is 8 and the second one is 6
Yes this is equal because 3v+v is 4v and if you divide 12v by 3 you also get 4v
You will want to round to 977.259
look at the number to the right of 9, it is 8, and 8 > 5. IF the number is 5 or greater, round up.
so your answer is 977.260
hope this helps
