Answer:

D. (∜(2x-8)^4=(-∜(2x+8)^4

Step-by-step explanation:

∜(2x-8)+∜(2x+8)=0

Rearrange the radical on the left side of the equation

∜(2x-8)=-∜(2x+8)

Raise both sides to the 4 power

(∜(2x-8))^4=(-∜(2x+8))^4

Determine the sign for exponential or radical expressions

(∜(2x-8))^4=(∜(2x+8))^4

Simplify the radical expression

2x-8=(∜(2x+8))^4

Simplify the radical expression

2x-8=2x+8

Rearrange variables to the left side of the equation

2x-2x=8+8

Apply the Inverse Property of Addition

0=8+8

Simplify

0=16

No solution

The step that makes the most sense is D. (∜(2x-8)^4=(-∜(2x+8)^4

P=2L+2W<br><br>solve for L <br>do the entire equation

VashaNatasha [74]

$HEY THEIR!!$

Taking commen 2 in RHS
p = 2 (L+W )

Divide by 2 on both sides.
p/2 = L+W

Subtract W on both sides.
p/2 - W = L

or L = p/2- W

Anna wants to take fitness classes. She compares two gyms to determine which would be the best deal for her. Fit Fast charges a

mestny [16]

Fit Fast: a set feet per class => y = Ax

Stepping Up: a monthly fee plus an additioal fee per class => h = Bx + C

You can discard the second and the fourth systems because they do not have the form established from the statement.

The first system produce an obvious result given that is represents an option that is always better than the other 5.5x will be lower than 7.5x + 10 for any positive value of x, and so there is no need to make any comparission.

The third system is

y = 7.5x and y = 5.5x + 10 which need to be solved to determine when one rate is more convenient than the other.

Answer: y = 7.5x and y = 5..5x + 10

(4k^4 + 2 - 3k) + (5k^4 + k - 8)

Sergeeva-Olga [200]

Hello!

You can only add values that have the same terms

4k^4 + 5k^4 = 9k^4

-3k + k = -2k

-8 + 2 = -6

The answer is 9k^4 - 2k - 6

Hope this helps!
