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

Answer: The correct answer is B because 0.7x=210, x=300
Step-by-step explanation:
210= 70% of the total distance to his grandfather's house, lets take that total distance for x.
So if:
210=0.7x
x=210/0.7
x=300
So,
First, find 1% by dividing 11 by 4.
11 * 0.25 = 2.75
Since 2.75 = 1%, we can simply move the decimal place two places to the right to get 100%.
2.75 --> 275
4% of 275 is 11.
