PLEASE HELP!!!!!!!!!!!!!!!!

Anton [14]

Answer:

<h2>1. subtract 3x, subtract 4, divide by -4</h2><h2 /><h2>2. add x</h2>

Step-by-step explanation:

1 + 3x = -x + 4.

subtract 3x

1 = -4x + 4

subtract 4

-3 = -4x

divide by -4

(-3)/(-4) = (4x)/(-4) ⇌ x = 3/4

-x + 6 = 5 - 3x

subtract 5

-x + 1 = - 3x

add x

1 = -2x

What is the simplest form of 6 radical 8 plus 8 radical 2

arsen [322]

Answer:

20 $\sqrt{2}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Simplify

$\sqrt{8}$ = $\sqrt{4(2)}$ = $\sqrt{4}$ × $\sqrt{2}$ = 2 $\sqrt{2}$

Thus

6 $\sqrt{8}$ + 8 $\sqrt{2}$

= 6(2 $\sqrt{2}$ ) + 8 $\sqrt{2}$

= 12 $\sqrt{2}$ + 8 $\sqrt{2}$

= 20 $\sqrt{2}$
