Answer:
Hello,
Step-by-step explanation:
![log(5-2x)=0\\\\\ \Longleftrightarrow\ 10^{log(5-2x)}=10^0\\\\\\\Longleftrightarrow\ 5-2x=1\\\\\Longleftrightarrow\ 2x=5-1\\\\\\\Longleftrightarrow\ x=\dfrac{4}{2}\\\\\\\Longleftrightarrow\ \boxed{x=2}\\](https://tex.z-dn.net/?f=log%285-2x%29%3D0%5C%5C%5C%5C%5C%20%5CLongleftrightarrow%5C%2010%5E%7Blog%285-2x%29%7D%3D10%5E0%5C%5C%5C%5C%5C%5C%5CLongleftrightarrow%5C%205-2x%3D1%5C%5C%5C%5C%5CLongleftrightarrow%5C%202x%3D5-1%5C%5C%5C%5C%5C%5C%5CLongleftrightarrow%5C%20x%3D%5Cdfrac%7B4%7D%7B2%7D%5C%5C%5C%5C%5C%5C%5CLongleftrightarrow%5C%20%5Cboxed%7Bx%3D2%7D%5C%5C)
The answer is C. 57 Minutes. I am pretty sure that’s correct.
Answer:
D
Step-by-step explanation:
The missing step is to perform the inverse of a square root by squaring both sides of the equation. This means to multiply 18*18=324 and the square root expression leaving just the inside untouched. The correct step is D.
Step-by-step explanation:
a^2+b^2=c^2
3^2+9^2 not equal to 12^2
