Answer:
8
Step-by-step explanation:
2log(x)=log(64)
By logarithms properties

log(x²)=log(64)
When you have log or ln in both sites, you delete them and...
x²=64
![\sqrt[]{x^{2} } =\sqrt{64} \\x=8](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7Bx%5E%7B2%7D%20%7D%20%3D%5Csqrt%7B64%7D%20%5C%5Cx%3D8)
X=30 degrees for each of the congregant angles
Slope of the line will be -3/2
Without the original equation, it's impossible to answer that question. I'm sorry.
Answer: x>-1
Step-by-step explanation: I know this because I solved this equation. I know that is not a good explanation but I know it is right.
