Answer:

A. \frac{x^2\sqrt{x}}{3}

Step-by-step explanation:

We have been given an expression \sqrt{\frac{2x^5}{18}}. We are asked to find which expression is equivalent to our given expression.

Let me simplify our given expression. First of all we will divide 18 by 2 as:

\sqrt{\frac{2x^5}{2\cdot 9}}

\sqrt{\frac{x^5}{9}}

Now we will rewrite x^5 \text{ as } x^4\cdot x.

\sqrt{\frac{x^4\cdot x}{9}}

Now we will write x^4\text{ and } 9 as perfect squares.

\sqrt{\frac{(x^2)^2\cdot x}{3^2}}

Let us factor our perfect square from square-root.

\frac{x^2\sqrt{x}}{3}

Therefore, option A is the correct choice.

A(-3,5) to B(8,1)

That makes a right triangle 8 - -3 = 11 in the x direction, 5 - 1 = 4 in the y direction.

d² = (8 - -3)² + (1 - 5)² = 11² + (-4)² = 121 + 25 = 146

d = √146 = 12.083045973594572

Answer: 12.1

A student solves the following equation for all possible values of x:
bekas [8.4K]
<span><u><em>The correct answer is: </em></u>
C) his solution for x is correct, but in order for 6 to be an extraneous solution, one denominator has to result in 0 when 6 is substituted for x.

<u><em>Explanation: </em></u>
<span><u>To solve this rational equation, we cross multiply: </u>
8*(x-4)=2*(x+2).

<u>Using the distributive property, we have </u>
8*x-8*4=2*x+2*2;
8x-32=2x+4.

<u>Subtract 2x from each side: </u>
8x-32-2x=2x+4-2x;
6x-32=4.

<u>Add 32 to each side: </u>
6x-32+32=4+32;
6x=36.

<u>Divide both sides by 6:</u>
</span></span>\frac{6x}{6}<span><span>=</span></span>\frac{36}{6}<span><span>;
x=6.

<u>Extraneous solutions</u> are solutions that come about in the problem but are not valid solutions to the problem; the only values of x that would give this sort of answer are -2 and 4, since these are the two values that would make one of the denominators 0 (we cannot divide by 0).</span></span>
