A piece of metal weighs 40g
has a volume of 4cm- 3 squared
What is it's density?

The density of the piece of metal is 10g/cm^3

Step-by-step explanation:

We know that we can write the density as:

Density = mass/volume.

In this case, we know that the mass is equal to 40g, and we know that the volume is equal to 4 cm^3

Then we can just replace these values in the above equation to calculate the density, this is:

Density = 40g/4cm^3 = 10 g/cm^3

Then the density of the piece of metal is 10g/cm^3

answer: 1 and 3

step-by-step explanation:

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
