A principal of $480 earns $108 interest in 5 years . what rate of interest was being paid?​

4.5%

Step-by-step explanation:

Solving our equation

r = 108 / ( 480 × 5 ) = 0.045

r = 0.045

converting r decimal to a percentage

R = 0.045 * 100 = 4.5%/year

The interest rate required to

accumulate simple interest of $ 108.00

from a principal of $ 480.00

over 5 years is 4.5% per year.

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!
