What expression is equivalent to 2(30x- 24),3(20x- 16), and 4(15x- 12)

Anyone know? is appreciated! will mark brainliest if correct!

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.

Can you me find the missing length. i attached an image.
