(3m2 + 8 - 3) + (n + 3) <br> Simplified

RUDIKE [14]

Answer:

$\boxed {3m^{2} + n + 8}$

Step-by-step explanation:

Simplify the following expression:

$(3m^{2} + 8 - 3) + (n + 3)$

-Subtract $3$ from $8$ :

$(3m^{2} + 8 - 3) + (n + 3)$

$3m^{2} + 5 + n + 3$

-Add $5$ and $3$ :

$3m^{2} + 5 + n + 3$

$\boxed {3m^{2} + n + 8}$

Therefore, the final answer is $3m^{2} + n + 8$ .
