Answer: 8:35
Step-by-step explanation:
<span>(serial number, model number)
That's a function mapping each serial number to its model number.
(part number, serial number)
That's not a function; the same part number is in computers with different serial numbers
</span><span> (model number, part number)
</span><span>
That one's a bit confusing. Normally a given model would have more than one part number inside so this isn't a function. But here the description says there's only one part number for each model, so that would be a function.
(model number, serial number)
Not a function, more than one serial number for a given model number.

Answer:
(x² - y² - 3xy) + (7xy + 3x²) = 4x² - y² + 4xy

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
(x² - y² - 3xy) + (7xy + 3x²)
<u>Step 2: Simplify</u>
- [Order of Operations] Combine like terms (x²): (x² - y² - 3xy) + (7xy + 3x²) = 4x² - y² - 3xy + 7xy
- [Order of Operations] Combine like terms (xy): (x² - y² - 3xy) + (7xy + 3x²) = 4x² - y² + 4xy
