Hope this helped you-have a good day bro cya)
what kind of question is that?
1 solution as the highest power on the unkown, x, is 1 so it’s a linear equation this causes it to have only 1 solution
i would say C. because since its 4 times the radius then you factor in thats only half of the circle then you factor in the other side which makes it 8 hope this is true
