1. D; -5m+2m, because -5+2=-3
2. B; 4 terms, every part of an expression that's not the subtraction/addition sign counts as a term.
3. Not 100% sure about this one, but I'll go with B; 4x².
4. C; 5b, that term cannot be combined because the variable is different from the rest.
I hope this was helpful.
Reduce the expression, if possible, by canceling the common factors.

Answer:
Polynomial Degree: 3
Step-by-step explanation:
log (m + n) = log m+ log n and proved it m =n/n-1
Given;
If log (m + n) = log m+ log n
To show that the m =n/n-1
Now, According to the question:
We know that,
Log (m + n) = log m + log n
Log (m + n ) = log (mn). [log a + log b = log ab ]
Cancelling the log on both sides.
then,
m + n = mn
=> n = mn - m
=> n = m (n - 1)
=> m = n / n - 1
Hence Proved
log (m + n) = log m+ log n and proved it m =n/n-1
What is Logarithm?
A logarithm is the power to which a number must be raised in order to get some other number (see Section 3 of this Math Review for more about exponents). For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2.
