Answer:
Step-by-step explanation:
Let the expression representing a situation is,
y = 6a + 2(c - b)
Where, a, b and c are the constants
If a = 2, b = 1 and c = 9
By substituting these values in the expression,
y = 6(2) + 2(9 - 1)
y = 12 + 16
y = 28
Therefore, for all given values of the constants value of y is 28.

2x² - 3x + 6 = 0
a = 2 b = -3 c = 6
delta = b² - 4ac = 9 - 4.2.6 = -39
The answer for the question is number A
2: 2, 4, 6, 8, 10
5: 5, 10
