Answer: 
Step-by-step explanation:
Given:
Since the denominator is a surd , to simplify , all we need do is to rationalize
That is
×
⇒ 
⇒ which is the simplified form of
First, set up an equation that models this statement.
N is your variable because it’s the unknown Number.
8n-13=43
Then, add 13 on both sides so you have the variable and it’s coefficient alone.
8n-13=43
+13.+13
________
8n=56
Then, divide the variable and the coefficient by the coefficient.
8n=56
—. —
8. 8
Now you have your variable all by itself, and you have the persons number.
n=7
Your number is 7.
1/3 because you have 3 different shape to choose from and you only need a square
Answer:
Center = (0, -10)
Radius = 4 units
Step-by-step explanation:
You have to divide the 3 because 6&9 have 3 in common which will leave you with square root a^2 c^3.
