The length l of the garden is three times its width w.

Three of these equations give the correct value for w.
Which equation does NOT?

CLEAR CHECK

w+3w=90

w+3w+w+3w=90

2⋅w+2⋅3w=90

2⋅(3w+w)=90

b) well because you get well

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

i would say b) is your answer

sorry if im wrong
