shutvik [7]4 years ago

Step-by-step explanation:

8x³+512

we know 512 is 8³. so: (2x)³+8³

now:

(2x+8)(4x²-16x+64)

I guess C might be the correct answer considering it may have been written wrong. because in the second braces we should do this:( (2x)²-(2x ×8) +8²) and 8²=64 not 16

The lines represented by the equations y = -X – 3 and
xz_007 [3.2K]

The equations y = -x -3 and 5y + 5x = -15 represents the same line option 'the same line' is correct.

<h3>What is linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have two equation of the line:

y = -x -3 and

5y + 5x = -15

From the equation 5y + 5x = -15:

Divide by 5 on the above equation:

y + x = -3

or

y = -x -3

The two equations y = -x -3 represents the same line.

Thus, the equations y = -x -3 and 5y + 5x = -15 represents the same line option 'the same line' is correct.
