I think the answer is :
3x^2 + 2 - x
i hope this helps :)
The volume of a cube is an edge length cubed, so an edge length would be the volume to the 1/3 power. Therefore, the edge length of this 1200 cm³ cube can be written as

cm. This also equals 2∛150 cm and is approximately 10.627 cm.
Standard Form is ...
ax + by = c
where a ≥ 0, b > 0 (if a=0), and {a, b, c} are mutually prime integers (unless irrational numbers are involved).
You can get there from where you're starting in a couple of steps. Multiply by the least common denominator of any fractions. (Here, you multiply by 4.) Then put the variable terms on the opposite side from the constant term. Make sure the leading coefficient is positive.
... 4y -4 = x -12
... x -4y = 8 . . . . add 12-4y
4. Option 3, a has length of infinity and mn does not split a, a splits mn
5. Option 2, only 1 possibility, since it has to split mn into equal parts
The area is 275 units squared
