The digit 2 is in the ten thousands place
the answer is a repeating decimal 31.1111111111 but just put 31.1
Yeah, base is ten and the two sides are 5...
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
