0=40-10t-5t^2
t^2+2t-8=0
(t+4)(t-2)=0
t=-4 (not a solution) or t=2
Answer: after 2 seconds
It would be 455 inches because you divide 5/2 and it is 2.5 then you multiply it by 182 which is 455
You have the following equation:

In order to solve the previous equation for y, proceed as follow:
3 + y/2 = -212 subtract 3 both sides
y/2 = -212 - 3 simplify right side
y/2 = -215 multiply by 2 both sides to cancel the denominator left side
y = -215(2)
y = -430
Hence, the solution for y in the given equation is y = -430
It is the number 16 because it has exactly five factors which are : 1,2,4,8,16. The number 4 repeats itself, therefore it is count as one number.
