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)

Answer:
The product rule is if the two "parts" of the function are being multiplied together, and the chain rule is if they are being composed. For instance, to find the derivative of f(x) = x² sin(x), you use the product rule, and to find the derivative of g(x) = sin(x²) you use the chain rule.

Answer:
A. No. B. 3
Step-by-step explanation:
A. The point is (4, 20) plug these into the equation with m being 2,
20=2(4)+8
20=8+8
20=16, this statement is not true, so m can't be 2.
B. 20=4m+8
-8 -8
12=4m divide by 4 on each side,
m=3
