Answer:

-15 + 10x

10x - 15

(either one works)

Step-by-step explanation:

You mean you just want me to expand it?

Ok.

Multiply -5 by 3 and -2x.

(-5)(3) = -15

(-5)(-2x) = +10x

Add those together:

-15 + 10x

10x - 15

Answer:

$\frac{6}{\sqrt 2}= 3\sqrt 2$

Step-by-step explanation:

Given

$\frac{6}{\sqrt 2}$

Required

Rationalize

$\frac{6}{\sqrt 2}$

To do this, we simply multiply by $\frac{\sqrt 2}{\sqrt 2}$

$\frac{6}{\sqrt 2} * \frac{\sqrt 2}{\sqrt 2}$

This gives:

$\frac{6 * \sqrt 2}{\sqrt 2 * \sqrt 2}$

$\frac{6 \sqrt 2}{2 }$

$3\sqrt 2$

Hence:

$\frac{6}{\sqrt 2}= 3\sqrt 2$

Describe how you would tell that two lines are parallel or coincide by looking at the equations of the lines in standard form.

Talja [164]

We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel.

Unlike parallel lines, perpendicular lines do intersect. Their intersection forms a right, or 90-degree, angle.
