Answer:
15 units
Step-by-step explanation:
Given the equation which models the path of a stone as:

At the time when the stone was thrown
x=0
Therefore:

The height of the stone at the time it is thrown is 15 units.
-3(x-5)=45
distribute
-3x+15 = 45
subtract 15 from each side
-3x = 30
divide by -3
x = -10
(x+2y)(x-5y)
do foil method:
x^2-5xy+2xy-10y^2
simplify x^2-3xy-10y^2,
so d is correct.
