Which expression is equivalent to 3 sqrt 27x^18
shusha [124]
Assuming your original expression was 3√(27x¹⁸), the answer is 9x⁹√(3).

We split up the radicand into perfect squares.  Once we do, we take out the things that were squared:
3\sqrt{27x^{18}} = 3\sqrt{3\times3\times3x^2x^2x^2x^2x^2x^2x^2x^2x^2x^2} = 3*3*xxxxxxxxx\sqrt{3}

=9x^9\sqrt{3}

Simplify the difference. (–7x – 5x^4 + 5) – (–7x^4 – 5 – 9x)
sineoko [7]

Answer: 2x^4+2x+10

Step-by-step explanation:

You need to remember the mulplication of signs:

(+)(+)=+\\(-)(-)=+\\(-)(+)=-

Knowing this, you can distributive the negative sign. Then you get:

(-7x- 5x^4 + 5) - (-7x^4 - 5 - 9x)=-7x- 5x^4 + 5 +7x^4 + 5 + 9x

Now you need to add the like terms. Then:

=2x+2x^4+10

Finally, you can order the polynomial obtained in descending order. Therefore, the answer is:

=2x^4+2x+10

BaLLatris [955]

Answer:

20

Explanation:

To know how many students will be in the country spelling bee, we need to find 5% of 400.

So, we need to multiply 400 by 5 and then divide by 100:

400\times5\text{ \%=}\frac{400\times5}{100}=\frac{2000}{100}=20

Therefore, there will be 20 students in the country spelling bee.
