Answer:
y= 1/2
Step-by-step explanation:
Given:
Length of a cube is 2 cm
To Find:
Surface area of the cube
Solution:
A cube consists of 6 faces.
The area of each face = side x side
So, the total surface area of a cube = 6 x
side x side
Let a be the length of the given cube
: Surface area of a cube = 6a square
a = 2 cm (Given)
Surface area of cube = 6 x 22 =(6 x 4) = 24 cm square.
Hence, the surface area of the given
cube is 24cm square.
Hope it helps!
-8x-8y=0 (divide both sides by -8, you get:) x+y=0, x=-y
-8x2y=-20 (divide both sides by -16:) xy=20/16=5/4
plug the first simplified equation into the second one,
-y²=5/4...This does not have a solution, are you sure you typed the second equation correctly?
