Answer 1

Your answers would be 8/3 (choice E) and -8/3 (choice A)

Answer 2

For this case we have the following expression:
 9x2-64 = 0
 Clearing x we have:
 9x ^ 2 = 64
 Dividing between 9 we have:
 x ^ 2 = 64/9
 Taking square root we have:
 x = + / - 8/3
 Answer:
 The solutions are:
 x = 8/3
 x = -8 / 3
