Answer:
A.
Step-by-step explanation:
EF^2=18^2-12^2
EF^2=324-144
EF^2=180
EF=root 180

The given statement can be represented as :
where, the number is assumed to be " b "
therefore, the correct choice is B. 2b³ - b
When you take the absolute value of this equation, the answer should actually be 3.
You should solve the what’s inside first. If the answer is negative, then the absolute value will make it positive.
For example
|1-5|=|-4|=4
