Given X = Y = 2Z, so Y = 2Z and X = 2Z as well. Then XYZ = (2Z)(2Z)(Z) = 4Z³ = 256, so Z³ = 64 and Z = 4. Therefore X = 2Z = 8. Option B (3), C (5), and D (6) don't satisfy the equation when substituted back.

Aristotle was the famous Greek philosopher who was appointed as the tutor for young Alexander the Great. He taught Alexander for several years, instilling in him a love for philosophy, literature, and science. Darius and Cyrus were Persian kings, while Socrates was Plato's teacher, not Alexander's.

Windows Vista was developed under the internal codename 'Longhorn'. This name was used throughout its development cycle before the official branding was announced. 'LongHund', 'Stackspray', and 'Pearl' are not recognized codenames for this specific Microsoft operating system.

A standard die has 6 faces numbered 1-6. Numbers greater than 4 are 5 and 6, giving 2 favorable outcomes. Probability = favorable/total = 2/6 = 1/3. Option A (1/2) would mean 3 numbers greater than 4, which is incorrect.

ATP stands for Adenosine Triphosphate, the primary energy currency of cells. It consists of adenosine bonded to three phosphate groups that store and release energy through bond formation and breaking. Adenine is just one component of adenosine, not the full name.

The verb phrase 'have trouble' is followed by a gerund (verb ending in -ing), not an infinitive. The correct construction is 'have trouble doing something,' making 'remembering my password' grammatically correct. Options A, B, and C incorrectly use infinitive or bare verb forms.

This is a sequence of the first letters of the English numbers: One, Two, Three, Four, Five, Six, Seven, Eight, Nine. The next number is Ten, which starts with the letter 'T'. The other options do not follow this logical pattern.

11158 divided by 77 gives remainder 70. To make it divisible, we need to add 77 - 70 = 7. Checking: 11158 + 7 = 11165, and 11165 / 77 = 145 exactly. Options A, B, and D would give remainders of 76, 77, and 75 respectively, not divisibility.
