abby and her 7 friends had lunch at the neighborhood burger barn. the bill was $47.60. if they shared the cost of the lunch equally, how much did each person pay?

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
