1. To evaluate a-b^2/b, substitute a = 10 and b = 2:
(10 - 2^2) / 2 = (10 - 4) / 2 = 6 / 2 = 3.
Therefore, the answer is b. 3.
2. To evaluate 3xy^2 - y, substitute x = 2 and y = 5:
3(2)(5^2) - 5 = 3(2)(25) - 5 = 150 - 5 = 145.
Therefore, the answer is d. 145.
3. To evaluate 2d + d^2/3, substitute d = 6:
2(6) + (6^2)/3 = 12 + 36/3 = 12 + 12 = 24.
Therefore, the answer is d. 24.
4. To evaluate (a-4b)^2 + 2a, substitute a = 15 and b = 3:
(15 - 4(3))^2 + 2(15) = (15 - 12)^2 + 30 = (3)^2 + 30 = 9 + 30 = 39.
Therefore, the answer is a. 39.
5. To evaluate (g + h)^2 + 10 / h, substitute g = 3 and h = 5:
(3 + 5)^2 + 10 / 5 = (8)^2 + 10 / 5 = 64 + 10 / 5 = 74 / 5 = 14.8.
Therefore, the answer is not among the given options.
6. To evaluate (c+d)^2/9, substitute c = 2 and d = 4:
(2+4)^2 / 9 = (6)^2 / 9 = 36 / 9 = 4.
Therefore, the answer is b. 4.
