Answer:
24 square meters.
Step-by-step explanation:
The surface area of the cube consists of 6 congruent squares with side length of 2 m.
The are of one such square is
![2\cdot 2=4\ m^2.](https://tex.z-dn.net/?f=2%5Ccdot%202%3D4%5C%20m%5E2.)
Hence, the surface area of the cube is
![6\cdot 4=24\ m^2.](https://tex.z-dn.net/?f=6%5Ccdot%204%3D24%5C%20m%5E2.)
Answers:
2x - 6y = 8 -> x = 4 + 3y
-3x + 9y = 12 -> x = -4 + 3y
Here, the equation of parabola is: (-36y)=x^2
The standard form of parabola is:
(X-h)^2=4p(y-k).
According to given equation, vertex = (0,0) and p = -9
This a vertical parabola opening down, because p = -9 here.
Therefore ditectrix will be y= -9
