1.) Use the formula to solve -
1/f = 1/do + 1/di; Where f = focal length; 1/do + 1/di
1/f = 1/do + di
1/8 = 1/25 + 1/?
.125 = .04 + 1/di
.125 -.04 = 1/di (transferred .04 to the left side of the equation)
.085/1 = 1/di
.085di/.085 = 1/.085 (multiplied both sides by di and divided both sides by .085)
di = 11.76 or 12
2.) Therefore, 12 cm is the distance from the image to the mirror
