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

<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>

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>
