F(gx)
f(-x-4) = 2(-x-4) + 3
F(-x-4)= -2x-8+3
F(-x-4)= -2x-5
G(fx)
G(2x+3)= -(2x+3) -4
G(2x+3)= -2x-3-4
G(2x+3)= -2x-7
F(hx)
F(x^2)=2x^2+3
H(fx)
H(2x+3)= (2x+3)^2
H(2x+3)= (2x^2) + 2(2x)(3)+3^2
H(2x+3)= 4x^2+12x+9
[I think I messed up with the last one. I didn’t know how to get the correct answer for that. Sorry ]

Answer:
her weekly allowance is $16
Step-by-step explanation:
Let x represent Imani's weekly allowance.
Imani spent half of her weekly allowance playing Mini-golf. This means that the total amount that she spent playing Mini-golf is x/2. The amount that she is left with would be
x - x/2 = x/2
In order to earn more money her parents let her wash the car for $4. This means that the total amount left with her is
x/2 + 4
if she ended with $12, it means that
x/2 + 4 = 12
x/2 = 12 - 4 = 8
x = 2 × 8 = $16
