Nikki is buying some refrigerator magnets for her friends. her total bill is $16.80. if magnets are $0.80 each, how many magnets is she buying?

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!

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
