Answer:
A simplified method for dividing a polynomial by another polynomial of the first degree is synthetic division.
Answer:
x = 1
Explanation:

Rule: log(a) + log(b) = log(ab)

cancel out log on both sides

relocate constant variable

take 3 as a common factor

divide both sides by 3

middle term split

factor common terms

collect into groups

set to zero

relocate variables

There must be a positive solution for log, so the solution is only x = 1
Answer:
U=3
Step-by-step explanation:
Since 9*3=27, and 27-7=20, U=3.
