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
Answer:
there are no seven in there
7x + 13 = 4x + 11 + 2x + 19
7x + 13 = 6x + 30
X = 17
7(17) + 13 = 132
Angle 3 is 132 degrees
