Hello!
Answer:
Step-by-step explanation:
First, expand.
Then, subtract by 18 both sides.
Simplify and solve.
Therefore, the solution to this equation is x=4, and x=-7.
x=4 and x=-7 is the correct answer.
Hope this helps you!
Have a nice day! :)
Thank you!
I think the remaining number is x
Answer:
2nd answer
Step-by-step explanation:
According to the logarithmic property of base change, the correpta answer is option one or the first.
The logarithmic property of base change says that
loga (b) = logc (b) / logc (a)
Therefore the same property applies to this problem and the correct expression for this question is:
logb (x) / logb (a)
Answer is A, y = 65
The top angle is 50 because 180 - 130 = 50
Since the top angle is 50, the two bottom angles have to add up to 130. Since the bottom angles are the same, you can do 130 / 2 to find the angles which equals 65.
