Two particles, Particle A and Particle B, begin traveling away from a wall. Let t represent the number of seconds since the particles started moving, let a(t) represent Particle A's distance from the wall in feet t seconds after the particles started moving, and let b(t) represent Particle B’s distance from the wall in feet t seconds after the particles started moving.

a. Suppose f(t) represents the particles’ combined distance from the wall in feet t seconds after they started moving. Define the function f in terms of a and b.
f(t) =

b. Suppose g(t) represents how much further Particle B is from the wall than Particle A (in feet) t seconds after they started moving. Define the function g in terms of a and b.

g(t) =

c. t seconds after the particles started moving, Particle A’s distance from the wall is h(t) times as large as Particle B’s distance from the wall. Define the function h in terms of a and b.

The zero product property states that if xy=0 then assume that x and y=0

so
factor into a form that is like taht
make one side 0
minus 7x both sides
x²-7x+12=0
what 2 numbers multiply to get 12 and add to get -7?
-3 and -4
(x-3)(x-4)=0

set equal to 0

x-3=0
x=3

x-3=0
x=4

x=3 or x=4

4th option
