Question

Number 9 I don’t understand

Answer 1

Answer: -177

Explanation:

The only mistake you made is inputting the q value (9) into the equation and thinking it wasn't negative. When there's a negative sign in front of the q, that doesn't change even after raising 9 to the second power. Because of this, it wouldn't be 81, it would be negative 81. Negative 81 minus 36 plus negative 60 would then equal negative 177. I hope this helped!! :)

Answer 2

`\huge\text{Hey there!}`

`\mathsf{-q^2 - r^2 + 3s}`

`\mathsf{= -9^2 - 6^2 + 3(-20)}`

`\mathsf{= -81 - 36 + 3(-20)}`

`\mathsf{= -117 + 3(-20)}`

`\mathsf{= -117 - 60}`

`\mathsf{= -177}`

`\large\text{Thus, this is why your answer should be: }`

`\huge\boxed{\mathsf{-177}}\huge\checkmark`
