Answer:
I'm not really sure but I think it's 2
Step-by-step explanation:
So here's what I did;
x³+3x-9=x - 1 +2x
x³+3x - x -2x = 9 - 1
x³= 8
x = ³√8
x = 2
I hope this helps
We have a right triangle.
Then:
A+B+C=90
Data:
C=90º
A=53º
Therefore:
53º+B+90º=180º
B=180º-53º-90º
B=37º
Answer: B=37º
To check:
Cos 37º=0.79863551...≈0.7986
The answer is B
The population is P
If it doubled it is 2P or 2 times P and that equals 12,000
