If sqrt x is around 3.4
x=(3.4)(3.4)=11.56
So x is in between 11 and 12 or
11
Hope this can help.
I would have guessed point S is (3,0).
(8-3)²-(5-2)²
Follow the PEMDAS
P-Parenthesis
E-Exponents
M/D-Multiplication/Division
A/S-Addition/Subtraction
clear the numerals in the parenthesis:
(5)²-(3)²
Now do the exponents:
=25-9
=16
Its just: (5)²-(3)²
