The key lies in translating "1/10 percent." If the unknown number is n, then 0.001n = 10. Mult. both sides by 1000: n = 10000 (answer)
The answer is -3 because -3+2=-1 then -1(4)=-4
Answer:

Step-by-step explanation:
1. You must clear the absolute value bars.
2. You have two cases: a positive case and a negative case.
3. First, you can solve the positive case as following:

4. Now, you must solve thie negative case as you can see below:

5. Therefore, the answer is:

Sadly, you didn't put any sums on your list of choices.
In fact, I can't even find a list of choices !
To find the distance between (7, -1) and (-8, -9),
you would build a sum under a square-root (radical)
symbol, and it would look something like this:
√ ( 225 + 64 ) .
24, 32 , 40. Divide through by 8
3, 4, 5,
The 3 , 4, 5 reminds of the Pythagorean triple, which is a right angled triangle.
So a triangle with sides 24, 32, 40 is a right angled triangle.
Option A.
