Answer:
B
Step-by-step explanation:
The answer is 3. While scale real height is 24 arm is 12. 24/2=12
So6÷2=3
P(x)=f(x)*g(x)
P(x)=(x-400)(1,200-2x)
P(x)=1,200x-2x^2-480,000+800x
P(x)=-2x^2+2,000x-480,000
Answer: Option <span>D. P(x) = -2x2 + 2,000x - 480,000</span>
The answer to your question is 18, how 20\100x90=18
