I need to know the dimensions to solve. Ex: "Line AC is 2.5 centimeters"
My bad - should've asked that under "Ask For Details."
Sorry :(
Let's consider an arbitrary 2x2 matrix as an example,

The columns of

are linearly independent if and only if the column vectors

are linearly independent.
This is the case if the only way we can make a linear combination of

reduce to the zero vector is to multiply the vectors by 0; that is,

only by letting

.
A more concrete example: suppose

Here,

and

. Notice that we can get the zero vector by taking

and

:

so the columns of

are not linearly independent, or linearly dependent.
The answer is C. 6x-24.

Answer:
AC ≈ 7.3
Step-by-step explanation:
Corresponding sides of similar triangles are proportional.
AC/BC = DF/EF
AC/18 = 15/37 . . . . fill in the given values
AC = 18(15/37) . . . multiply by 18
AC ≈ 7.3
