1. The given expression is $12t + 20$. 2. This is a linear algebraic expression in terms of $t$. 3. To analyze it, we can describe it as a function $f(t) = 12t + 20$. 4. There is no equation to solve or simplify further as the expression is already in its simplest form. 5. If you want to graph this function, it is a straight line with slope $12$ and y-intercept $20$. 6. The slope means for every increase of $1$ in $t$, $f(t)$ increases by $12$. 7. The y-intercept is the value of $f(t)$ when $t = 0$, which is $20$. Final statement: The expression $12t + 20$ represents a linear function with slope $12$ and y-intercept $20$.
