Hope I helped:)
Distribute 9z to 7z and -4
You get 56z^2 - 36z = 6
56^2 - 36 - 6 = 0
Solve using quadratic formula
z is approx 0.78 and approx. -0.14
The first one is correct (-2/3, -1/2, 7/12, 0.82) pls mark branliest
Answer: 16875x³-13500x²+3600x-320
Step-by-step explanation:
[gοfοh](x) means g(f(h(x))). So you plug in h(x) into f(x) and that into g(x).
f(3x)=5(3x)-4=15x-4
g(f(3x))=5(15x-4)³
g(f(3x))=5(3375x³-2700x²+720x-64)
g(f(3x))=16875x³-13500x²+3600x-320
