How can we find different ways to present algebraic expressions without changing

The algebraic expressions can be presents by words or equivalent expressions, so that its meaning remains same.

Step-by-step explanation:

Different ways to present algebraic expressions without changing their meaning:

1. We can describe the algebraic expressions in words so that its meaning remains same.

For example : 3x+y = Sum of 3 times of an unknown variables x and y.

2. We can describe the algebraic expressions in equivalent expressions, so that its meaning remains same.

For example : 6x+3y = 3(2x+y)

Therefore, the algebraic expressions can be presents by words or equivalent expressions, so that its meaning remains same.

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z > the scale factor

VA ---> volume of the sphere A

VB ---> volume of the sphere B

so

we have

substitute

That means> The volume of the sphere B is 8 times the volume of the sphere A

therefore

The ratio of the volume of sphere A to sphere B is
