Final answer:
For the expression -3 + x^2 with x=6, the answer is 33 (Option C).
For the expression -2 + 2x^3 with x=6, a mistake seems to have occurred as the answer 430.
Step-by-step explanation:
The first expression to evaluate is -3 + x^2 for x = 6. To evaluate, replace x with 6 and calculate:
The simplified answer is 33, which corresponds to option C.
The second expression to evaluate is -2 + 2x^3 for x = 6. Here's the step-by-step calculation:
- -2 + 2*(6)^3
- -2 + 2*216
- -2 + 432
- 430
This yields the simplified answer of 430, which is not listed in the options provided. It seems there is an error in the given options for this expression.
