See a solution process below:

For each of occurrence of $color(red)(s)$ in the expression substitute $color(red)(7)$

For this problem the variables $a$ and $m$ and $t$ are extraneous or not used and therefore not needed.

$(color(red)(s) + 1)(color(red)(s)^2 - color(red)(s) + 1)$ becomes:

$(color(red)(7) + 1)(color(red)(7)^2 - color(red)(7) + 1) =>$

$8(49 - color(red)(7) + 1) =>$

$8 * 43 =>$

$344$
