Answer:
B) f(g(x)) = 15x² + 18
Step-by-step explanation:
Plug the entire equation of g(x) in for the x in f(x)
f(g(x)) = 5(3x² + 3) + 3
f(g(x)) = 15x² + 15 + 3
f(g(x)) = 15x² + 18
This is the answer: false, because the domain is incorrect
I think the answer is b because i subtracted

Answer:
Step-by-step explanation:
<u>As per diagram we have:</u>
<u>As per 30° right triangle property:</u>
- CD = √3×CB/2 = 3√3 ≈ 5.2 cm
- and
- AC = 2CD = 2×5.2 = 10.4 cm
<u>Area of triangle:</u>
- A = 1/2bh
- A = 1/2CB*AC
- A = 1/2*5.2*10.4 ≈ 27 cm²
