Step-by-step explanation:
log18 = log2 + log3 + log3 = x + 2y.
log9 = log3 + log3 = 2y.
Their slopes must be the same, but with different y-intercepts.
Here is an example: 2x + 1 and 2x + 4 are parallel lines.
I took a test on this yesterday and all i know is the answer is either 81 117 or 162
The edge length of the cube is 0.4
