Please use " ^ " to indicate exponentiation: x^2 + 3x - 4 = 0
Here, a = 1, b = 3 and c = -4.
The formula for the discriminant is b^2 - 4(a)(c).
Substituting the given values of a, b and c, we get:
(3)^2 - 4(1)(-4)
Evaluating this, we get 9 + 16 = 25.
The discriminant is 25.
-3 plus or minus √25
Taking this further, x = ------------------------------------
2
-3 plus or minus 5
or: x = -------------------------------- => {-4, 1} (solutions)
2
Not 100 % but I would think as likely as not because you have the same amount of both. 1/2 the chance
B would be the answer for sure
Let number of Adult ticket be x
and number of Child ticket be y
so
$282 = $24x + $18y.

Based on the wording of the question, I believe that the answer allows you to pick more than one. However, there still may only be one answer.
