Answer:
B
Step-by-step explanation:
The answer is obviously B =-=
Answer: -9
(-3) ³= -27
6 ³/12 = 216/12 = 18
-27+18=-9
Perfect-square trinomials are of the form:
and are expressed in squared-binomial form as: 
The only possible choice for squared-binomial form is
Answer: correct choice is A.
The thickness of a fingernail is about 10^-5 inch
From the complete question, we have the following parameter
Thickness = 1/100000 inch
To represent the thickness in standard form, we do the following:
Express the thickness as a decimal
Thickness = 0.00001 inch
So, the standard form would be:
Thickness = 1 * 10^-5 inch
This gives
Thickness = 10^-5 inch
Hence, the complete statement is:
The thickness of a fingernail is about 10^-5 inch
