Use ur fingers and add three use the strategy hope this helped

A scale factor of 2 means the dimensions are multiplied by 2.
15 x 2 = 30
8 x 2 = 16

Answer: D) -3</h3>
Explanation:
Recall that y = f(x) since both are outputs of a function.
If k = 2, then f(x) = 2 leads to y = 2 being a horizontal line drawn through 2 on the y axis. This horizontal line only crosses the cubic curve at one spot. The same can be said if k = 0 and k = -2. So we can rule out choices A,B,C.
On the other hand, if k = -3, then f(x) = -3 has three different solutions. This is because the horizontal line through -3 on the y axis crosses the cubic at 3 different intersection points.
Its 12y - 9 because when u add twelve pluus 12 it 24 then -21 is to 3 which 12 - 9 is 3
