Answer:
C or A
Step-by-step explanation:
The polynomial to be added to –7mn + 2m² + 3n² to obtain 5m² + 2mn - 9n² is: 3m² - 11n² + 9mn.
<h3>Addition of Polynomials</h3>
Like terms should be combined together when adding polynomials.
Let x represent the polynomial expression that would be added to –7mn + 2m² + 3n² to obtain 5m² + 2mn - 9n².
Therefore:
–7mn + 2m² + 3n² + x = 5m² + 2mn - 9n².
x = 5m² + 2mn - 9n² - (-7mn + 2m² + 3n²)
x = 5m² + 2mn - 9n² + 7mn - 2m² - 3n²
Combine like terms together.
x = 3m² - 11n² + 9mn
Therefore, the polynomial to be added to –7mn + 2m² + 3n² to obtain 5m² + 2mn - 9n² is: 3m² - 11n² + 9mn.

Answer:
The other number is 22.
Step-by-step explanation:
66 is the lowest common multiple of 6 and a number between 15 and 25.
The numbers between 15 and 25 include 16, 17, 18, 19, 20, 21, 22, 23 and 24.
Of all these numbers between 15 and 25, only 22 can divide 66 without a remainder.
And conveniently, the lowest common multiple of 6 and 22 is 66.
Hence, the other number is evidently 22.
