X=9 -12 divided by -4 is -3, so you get -3x=-27. When you divide -27 by -3 you get positive 9. Thus making X=9
Pir^2=100
I will use 3.14 as pi
R^2=31.84713375796178
R=5.643326479831003
The max radius is about 5.64 feet
4A^4+6A^3B^2+2A^2B^3
2A^2(2A^2+4AB^2+B^3)
I think your equation is wrong. the domain of f(x)= 5x+2 is ALL REAL NUMBERS. That means it’s negative infinity to positive infinity.
