Answer:
Assuming that the last four numbers are answer choices, your answer would be 11
Step-by-step explanation:
9/11 rounds up to 1, 1 + 18 = 19
3/8 rounds down, so you only have 8 for that one
19 - 8 = 11
<u>Given</u>:
The given expression is 
We need to determine the equivalent number.
<u>Equivalent expression:</u>
To determine the equivalent number, let us solve the expression 
Thus, let us apply the exponent rule
, we get;

Also, the term 10³ can be written as 
Thus, we get;

Dividing, we get;
0.001
Hence, the equivalent number is 0.001
Hence, Option c is the correct answer.
Factor
(x-8)(x+3)
Check:
-8+3=-5
-8*3=-24
Use ZPP
x-8=0
x=8
x+3=0
x=-3
Final answer: x=-3, x=8
Multiply the two, and you will have 3/500. It’s already as simplified as it can be so that is the answer.
