Answer:

[tex] \frac{50}{5} = 10[/tex]

Step-by-step explanation:

[tex] \frac{7(8 - 1) + ( - 1 {)}^{2} }{1 + {2}^{2} } [/tex]

[tex] \frac{7 \times 7 + ( - 1 {)}^{2} }{1 + {2}^{2} } = \frac{7 \times 7 + 1}{1 + {2}^{2} } [/tex]

[tex] \frac{7 \times 7 + 1}{1 + 4} = \frac{49 + 1}{1 + 4} = \frac{49 + 1}{5} [/tex]

[tex] = \frac{50}{5} = 10[/tex]
