Answer:
$9.89
Step-by-step explanation:
If you follow PEMDAS, multiplication would be first, so 3*2 is 6, then it's addition.
So 3*2=6 and 8*-16 is -128, then you add them both.
So 6+(-128) is equals to -122. YOU'RE WELCOME :D
Given the following functions below,

Factorising the denominators of both functions,
Factorising the denominator of f(x),

Factorising the denominator of g(x),

Multiplying both functions,
(5,1) Is Point Form.
Via; Equation Form:
x = 5,y = 1
I used Solve the System of Equations to solve
Use the Pythagorean theorem
A^2+b^2=c^2
12^2+5^2=c^2
144+25=c^2
169=c^2
13=c
