Answer 2

$\huge\textbf{Hey there!}$

$\mathbf{-3pq^2 + q^3}$

$\mathbf{= -3(2.9)(-1.3)^2 + (-1.3)^3}$

$\mathbf{= -3(2.9)(-1.3)^2 - 1.3^3}$

$\mathbf{= -8.7(-1.3)^2 - 1.3^3}$

$\mathbf{= -8.7(1.69) - 2.197}$

=$\mathbf{ -14.703 -2.197}$

$\mathbf{= -16.9}$

$\huge\textbf{Thus, your answer should be: \boxed{\mathsf{-16.9}}}}\huge\checkmark$

$\huge\textbf{Good luck on your assignment \& enjoy}\\\huge\textbf{your day!}$
