The answer is A. <span>x = 5 because if you multiply 5 by itself 3 times i equals to 125.

<span>The pitch of the roof is one of the two major measures of roof angle, the other being slope. In order to calculate the roof pitch as a fraction, one should divide the rise of the roof by the span, which is defined as the length between the exterior of the top plate of one wall and that of the corresponding wall on the other side of the building.</span>
The set is linearly dependent.
To explicitly prove this, we need to show there is at least one choice of constants 
such that
or equivalently,
which is the same as solving the system of equations
From the first and last equations, we have 
and 
. Substituting these into the second equation leaves us with 
, and so the overall solution set is
for which there are infinitely many not-all-zero solutions.
