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:
Answer c) (13)
Step-by-step explanation:
Begin with 3x+2x-45=20. Go through the steps of solving this for x.
Combining like terms, we get 5x = 65.
Dividing both sides by 5, we get x = 13.
Answer c) (13) is the correct answer/solution/root.
X=2
inscribed angle - 3(2)+4=10
arc - 10(2)=20
the Arc is two times the inscribed angle
