Estimate by rounding to the nearest hundred.<br>Show your work.<br>12,846 - 3467​
Rufina [12.5K]

Answer:

9,400

Step-by-step explanation:

12,846 - 3,467 = 9,379

The hundreds digit is 3.

So, you look to the left of the digit and if it is 5 for more you add a number to the 3 and make the rest of the digits 0s. But if it below 5, then you leave the 3 alone and make the rest of the digit going to the right 0s.

Then, your answer is (9,400)

Hope this helps ; )

For P(x) divided by (x - 1) , then the remainder is P(1) = 0

For P(x) divided by (x + 2) then the remainder is P(- 2) = 1
