50 points precalc math, please please help me I haven't been able to solve this in 2 days. I've looked everywhere and asked so many ppl to no avail :'(

This doesn’t make sense to me it’s supposed to be lcm ( least common multiple )

Use the distributive law to multiply. 3(4x + 5y + 6)

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
