Answer: D
Step-by-step explanation:
A seems complicated and doesn’t make an sense while D is simple
It lands on floor 5.
10-9+19-3-12
1+19-3-12
20-3-12

( y - 4 ) ( y² + 4 y + 16 ) =
= y³ + 4 y² + 16 y - 4 y² - 16 y - 64 = y³ - 64
If the result is the polynomial of the form:
y³ + 4 y² + a y - 4 y² - a y - 64
a = 16
The slope is 4/2, simplify to 2/1 or 2.
