2 answers:
Answer:
The estimated value is 0.01.
Step-by-step explanation:
Given : 17 divided by 1,569.
To find : Use compatible number to find two estimates ?
Solution :
Compatible numbers are pairs of numbers that are easy to add, subtract, multiply, or divide mentally.
Estimation is to approximate a calculation.
Estimating the number 17 is 20.
Estimating the number 1569 is 2000.
Substituting the values,
20 divided by 2000,
Therefore, The estimated value is 0.01.

Answer:
5x² +19x +76 +310/(x-4)
Step-by-step explanation:
The process is straightforward. Find the quotient term, multiply it by the divisor and subtract from the dividend to get the new dividend. Repeat until the dividend is a constant (lower-degree than the divisor).
The tricky part with this one is realizing that there is no x-term in the original dividend, so that term needs to be added with a 0 coefficient. The rather large remainder is also unexpected, but that's the way this problem unfolds.

Unlike numerical long division, polynomial long division is simplified by the fact that the quotient term is the ratio of the highest-degree terms of the dividend and divisor. Here, the first quotient term is (5x^3)/(x) = 5x^2.
