Help I really want a good grade.

So for this expression, remember PEMDAS
Firstly, start with solving inside the parentheses: [tex] 2^3-6+9 [/tex]
Next, solve the exponent: [tex] 8-6+9 [/tex]
Now that we only have addition and subtraction, solve it from left to right to get your answer:
[tex] 8-6+9 \\ 2+9 \\ 11 [/tex]
Your answer is 11.
Hey there!
