$\boxed{phoebe \: is \: right }:$

Step-by-step explanation:

$the \: slope \: \boxed{ \: m} \: o f \: a \: line \: is \: given \: by \to \\ \boxed{m = \frac{y_{2} -y_{1} }{x_{2} - x_{1}} } \\ if \: the \: points \: are \to \\ (x_{1} ,\: y_{1}) = (12, \: 5) \\ (x_{2}, \: y_{2}) = (12, \: 9) \\ the \: slope \: \boxed{m} \: is \to \\m = \frac{ 9-5 }{12 - 12} \\ m = \frac{4}{0} \: \\ \boxed{hence \: the \: slope \: is \: undifined }: \\ \boxed{since \: the \: denominator \: is \: zero \: (0)}$

Answer: $a(x) = x^2 + 40 x + 384$

Step-by-step explanation:

Since, here the length of the rectangle is represented by the function l(x) = x + 24,

While the breadth of the rectangle is represented by the function w(x) = x + 16.

And, we know that the area of the rectangle = length of the rectangle l(x) × breadth of the rectangle.

a(x) = l(x) × w(x)

a(x) = (x + 24) × (x + 16)

$a(x) = x^2 + 24 x + 16 x + 24\times 16$

$a(x) = x^2 + 40 x + 384$
