A hovercraft takes off from a platform. Its height (in meters), x seconds after takeoff, is modeled by:
h(x)=-3(x-3)^2+108
How many seconds after takeoff will the hovercraft land on the ground?

none cuz there are no "following statements" regarding the question

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

#12 the answer is the third option
