O 5.7
O 6.3

Answer 1

Answer: -6.3

Explanation:

`-12+\sqrt{32\\`

`-12+2^2\sqrt{2`

`-12+4\sqrt{2` and that is approx -6.3

Answer 2

Hello There ~

For this, we need to evaluate the approximate value of root 32, that is equal to : 5.65

we simply need to put the approximate valuw in expression and find the result.

`\longrightarrow \tt - 12 + √(32)`

`\longrightarrow \tt - 12 + 5.65`

`\longrightarrow \tt - 6.34`

`\longrightarrow \tt \approx - 6.3`

Hence, the first option over there is the most suitable choice.
