Answer:
-21 + 16 = -5
Step-by-step explanation:
7(-3) + (-4)[tex]^{2}[/tex]
Multiply the 7(-3), and the answer will be negative because we are multiplying a pos to a neg.
-21 + (-4)[tex]^{2}[/tex]
Do the exponent, this will be a positive because the exponent is by two so we multiply (-4) by (-4) so the signs match.
-21 + 16
Now solve.
-21 + 16 = -5
