How would you plot x(t)=[12+7sin(t-(1/3*pi)]*cos(13pit)

If you have symbolic math toolbox, you can use fplot.
syms t;
x = (12 + 7*sin(pi*t - (1/3)*pi) )*cos(13*pi*t)
x = 
fplot(t,x)

Try this:
t = linspace(-pi, pi, 1000);
xt = (12 + 7 * sin(pi * t - (1/3 * pi))) .* cos(13 * pi * t);
plot(t, xt, 'b-', 'LineWidth', 2);
grid on;
xlabel('t', 'FontSize', 20);
ylabel('x(t)', 'FontSize', 20);
