3x - 45 = 2x + 5
3x - 2x = 5 + 45
x = 50
4y - 1 + 2x + 5 = 180
4y + 2(50) + 4 = 180
4y = 180 - 4 - 100 = 76
y = 76/4 = 19.
y = 19
Answer:
they all look the same to me just turned and smaller
If it's really a cube, then it can have only one set of dimensions.
Actually, only one dimension ... the length of every edge is the
same number.
The volume of a cube is the cube of its edge length. So the
length of every edge is the cube root of its volume.
But the dimension can sometimes be written in different ways.
Volume = 360 inch³
Edge length = ∛(360 inch³)
= ∛360 inches
= 3 ∛(13 and 1/3) inches
= 4 ∛5.625 inches
= 5 ∛2.88 inches
= 6 ∛(1 and 2/3) inches .
