the complete question is
Janet has a square-shaped sheet of wrapping paper. To cover the top of a box, she cuts off 11 centimeters of the sheet along the width. The new area of the sheet is given by the expression below, where x represents the length, in centimeters, of the sheet of wrapping paper before being cut.
x²-11x
Which statement best describes the term 11x?
the area cut from the sheet of wrapping paper
the area of the sheet of wrapping paper after being cut
the area of the sheet of wrapping paper before being cut
the width of the sheet of wrapping paper after being cut
we know that
initially
the dimensions of the sheet of paper are
length-------> x cm
width--------> x cm
Initial Area=x² cm²
after the cut
the dimensions of the sheet of paper are
(x-11) cm * x cm
New Area=(x-11)*x------> (x²-11x) cm²-----> New Area=Initial Area-11x
therefore
the answer is the option
the area cut from the sheet of wrapping paper
, and the relation of the tangent with the sine and cosine:
, you get:
