Answer:

8w^2 I don't know why it is not on here, but I put it in an algebra calculator and everything. Good luck. :)

Step-by-step explanation:

Simply the radicals by multiplying and taking square roots.

2 $\sqrt[4]{8w^3}$ * $\sqrt[4]{32w^5}$

= 2 $\sqrt[4]{8w^3}$ *2w $\sqrt[4]{2w}$

= 4w $\sqrt[4]{16w^4}$

=4w(2w)

= $8w^{2}$

Substract 6 to both sides and you get 36 =-2d then you use the multiplicative inverse and d=-18.

Which of the following best describes the solution to the system of equations below?

liraira [26]

For this case we have the following system of equations:

$6x + 3y = 6\\6x + 3y = 14$

We multiply the first equation by -1:

$-6x-3y = -6$

We have the following equivalent system:

$-6x-3y = -6\\6x + 3y = 14$

We add the equations:

$-6x + 6x-3y + 3y = -6 + 14\\0 = 8$

Equality is not fulfilled, so the system of equations has no solution.

I am honestly not sure about this answer... try Khan Academy. Or, try breaking it down into steps.

I hope this helped... sorry about that. I will try this concept soon. :)
