The image of an object is located 6cm behind a convex mirror. If it's magnification is 0.6, calculate the focal length of the mirror

Just a single mistake, can destroy a whole solvings

Since it is a convex mirror,the image will be negative

what are you guys doubting?
myschool is corrrect
the image will be negative since it is a diverging lens(Convex) but assuming its a Converging less (Concave) it will be positive

pls check your textboooks

This is not right naahh!!!..
This is a convex mirror. Meaning the image is negative because it's formed behind the mirror .

Once we go that way.. our answer bcomes.. D

But according to all sources I've checked focal length and image distance of a convex mirror is positive and for a concave mirror is negative. Also, I've seen multiple sources say that the formula for magnification for mirrors is m= -v/u that the formula m=v/u are for lenses.

A is the correct answer

Why can't we use the formula
M=V/F -1

the answer is A and not d corrections should be made reason
behind convex mirror is positive and not negative and if u do your calculations the answer is 3.75

(1/10)+(1/-6)...... it equals (-4/-60)..... am I wrong abi my Maths is terrible

guys they said that the lcm is 60 instead of 30 that is why they got 15, it is suppose to be 3.75, -3.75
