the asnwer is A
Step-by-step explanation:
Answer:
20 cm
Step-by-step explanation:
A cube has 6 faces. Two of the faces are bases. The other four faces are lateral faces.
Let the area of 1 face = x
4x = 1600 cm^2
x = 400 cm^2
Since the area of 1 face is 400 cm^2, then the side length is sqrt(400 cm^2) = 20 cm
Answer: 20 cm

When y varies inversely as x it can be expressed as follows:
If we write the general equation for this
When y=3 and x=4 we can calculate de value of A
Then the equation that describes an inverse variation between x and y is_
