Answer:
D. None of the choices are correct.
Step-by-step explanation:
If <em>B</em> is the midpoint of AC, then that means that AB is congruent to BC. Because this is true, you can set 8x + 4 and 10x - 8 equal.
8x + 4 = 10x - 8
Now just solve for x. Subtract 8x from both sides and add 8 to both sides.
4 = 2x - 8
12 = 2x
Then divide by 2.
6 = x
Another way to do this problem is to set up the same equation, but instead of solving it, plug in answer choices A, B, and C independently of each other. Then simplify to see if those are right. You'll find out that none of them are.

Answer:
A base of ten raised to a negative exponent corresponds to a number that is between 0 and 1.
Step-by-step explanation:
A base of ten raised to a negative exponent, say - 1 will correspond to the number, 
.
Again, a base of ten raised to a negative exponent, say - 2 will correspond to the number, 
.
{Since we know the property of exponents as 
}
Therefore, all those numbers are between 0 and 1.
Hence, a base of ten raised to a negative exponent corresponds to a number that is between 0 and 1. (Answer)
