The expression (-4x + 9)^2 cannot be equal to (-4x)^2 + 9^2 because it is actually equal to the product of two factors (3 + 2sqrt x) (3- 2 sqrt x). One cannot use obviously distributive property. Hence the answer to this problem should be C. as she did not understand both perfect square trinomial and did not determine the product

Not sure wym but if u can't write the format just write the numbers out in spanish: uno dos tres cuatro cinco seis siete ocho nueve diez
Absolute value simply removes the sign from a number making both negative and positive numbers positive. That means that the absolute value of both a positive and a negative number have the same value.
That means |-7| = 7 and |7| = 7
So |-2| = 2 and |2| = 2
|1/3| = 1/3 and |-1/3| = 1/3
