Final answer:
The correct answer to evaluate the expression 3x^2 + 10a + 5b + 7 for x = 3, a = 0, and b = 2 is 44, which does not match any of the provided choices.
The correct answer is none of all.
Step-by-step explanation:
We are asked to evaluate the expression 3x2 + 10a + 5b + 7 for x = 3, a = 0, and b = 2. To do this, we substitute the given values into the expression:
3(3)2 + 10(0) + 5(2) + 7
= 3(9) + 0 + 10 + 7
= 27 + 0 + 10 + 7
= 27 + 17
= 44
None of the answer choices a) 92 b) 90 c) 84 d) 70 match the correct answer, which is 44.
