Svetlanka [38]

Answer:

Option 3) area space occupied by any sample of matter              

Step-by-step explanation:

We define volume of an object as:

  • It is defined as the space occupies by an object.
  • It is measured in cubic units.
  • It is the quantity of three-dimensional space enclosed by a closed surface.
  • It is different from mass occupied by the object.
  • Thus, it is defined as:

Option 3) area space occupied by any sample of matter

It is not a unit for measuring distance.

It cannot be defined as amount of matter in an object force per unit

Identify the polynomial x^3-y^3+z
Vaselesa [24]

Answer:

Hi there!

The answer to this question is:

Standard: y= x- (cube root) z

the leading coefficient: 1

Step-by-step explanation:

when identifying a polynomial you always need to know the standard equation, and leading coefficient.

-you first need to know what "y" so you move y to the other side by adding it on both sides

-then you need to get y by itself and cube root it on both sides resulting in x^3 becoming x and z becoming (cube root) z
