Answer:

b/a = 3

Step-by-step explanation:

f(x) / (x²-4x-12) = Q(x) + (x+6)/(x²-4x-12)

f(x) = Q(x)*(x²-4x-12) + (x+6)

x= - 2 ... when f(x) is f(-2) x²-4x-12 = 4+8-12 = 0

a = f(-2) = Q(x)*0 + (-2 + 6) = 4

x= 6 ... when f(x) is f(6) x²-4x-12 = 36-24-12 = 0

b = f(6) = Q(x)*0 + (6 + 6) = 12

b/a = 12/4 = 3

Mark has seven tickets. Hannah gives him six more tickets. how many tickets does Mason have in all?

Zanzabum

If Mark starts with 7 tickets, and Hannah gives him 6 more, then Mark has 13 tickets total. The equation for this problem looks like this:

7+6=13.

Mason, on the other hand, has none, because Hannah didn’t give him any, and the question never mentions him buying any.
