363 rounded to the nearest ten would be 360
The true statement is (b) she did not represent the two original factors correctly on the headers
<h3>How to determine the true statement?</h3>
The product expression is given as:
(-2x - 1)(2x - 1)
Expand the expression
(-x - x - 1)(x + x - 1)
This means that the header of the algebra tiles would be:
-x, -x, 1 and x, x and -1
From the figure, we can see that this is incorrectly represented
Hence, the true statement is (b)
