Answer:
-57
Step-by-step explanation:
<h2><u>Use BOMAS</u></h2>
B- brackets
O- of
M- multiplication
A- addition
S - subtraction
-3[1+2(4+5)]
first solve what is in the brackets
(4+5) = 9
place 9 in the brackets
-3[1+2(9)]
now multiply the 2 and 9
2*9 = 18
-3[1+18)]
1+ 18 = 19
now multiply the (-3) with 19
= <u>-57</u>

Step-by-step explanation:
<u>Step 1: Define</u>
g(x) = -x² + 10x - 3
g(9) is x = 9
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: g(9) = -(9)² + 10(9) - 3
- Exponents: g(9) = -(81) + 10(9) - 3
- Multiply: g(9) = -81 + 90 - 3
- Add: g(9) = 9 - 3
- Subtract: g(9) = 6
B) An example..... It would be better to explain and give an example to what your trying to say.
