Answer 1

Answer: 7

Explanation:

7+4+(3)^2-5(3)+2=

11+9-15+2=

20-15+2=7

Answer 2

`\huge\text{Hey there!}`

`\mathsf{7 + 4 + f^2 - 5f + 2}`

`\mathsf{= 7 + 4 + 3^2 - 5(3) + 2}`

`\mathsf{= 7 + 4 + 9 - 15 + 2}`

`\mathsf{= 11 + 9 - 15 + 2}`

`\mathsf{= 20 - 15 + 2}`

`\mathsf{= 5 + 2}`

`\mathsf{= 7}`

`\huge\textbf{Therefore, your answer should be: }`

`\huge\boxed{\mathsf{7}}\huge\checkmark`
