R(x)-c(x)=x²-30x+20 choose C
Answer:
x-12
Explanation:
I thought about it, and just flipped the numbers. I use an online grading system to check it, so I am pretty confident I am correct.
Zero because -12 does not equal 12
True because tan(20)=2.1 and cot(20)=is o.44
We need to divide for this. Since there are 12 months in a year, we divide his yearly salary by 12.
270,920.64÷12=22,576.72
So, Mr.Castillo's monthly salary is $22,576.72.
