Martin needs 60 meters of fence to go around a rectangular garden.
The length, l, of the garden is twice its width w.
Three of these equations give the correct value for w.

Which equation does NOT?

your answer is -9

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

false, it is 3

-35* 3 = -105
