The characteristic polynomial is given by 
:
Compute the determinant by Laplace expansion along the first row:
Answer:
B
Step-by-step explanation:
When you multiply 2 equations together, you just multiply them. You'd get x(3x-20) = 3x^2 - 20x, which is B

Answer: Choice A) e^c = 4</h3>
=====================================
In general if we had something like x = ln(y), then it is equivalent to e^x = y or y = e^x. The Ln is a natural log that is the inverse of the base e exponent. It's a special kind of log.
In this case, x = c and y = 4
So we go from c = ln(4) to e^c = 4
note: Logs are often used to solve for equations with variables in the exponent.
Q=56??? Sorry if it’s wrong lol
