Answer:
[tex]\boxed{\boxed{\sf 698}}[/tex]
Step-by-step explanation:
[tex]\sf 3(14+c^2)+2d[/tex]
[tex]\longmapsto\sf c=12[/tex]
[tex]\longmapsto\sf d=112[/tex]
Substitute c with 12, and d with 112:
[tex]\Box \:\: \sf 3\left(14+12^2\right)+2\times \:112[/tex]
we'll follow the PEMDAS order of operations:
→ Parentheses
→ Exponents
→ Multiplication
→ Division
→ Addition
→ Subtraction
