Answer:
- 2 terms
- second coefficient: 30
Explanation:
You want the number of terms and the second coefficient in the expression ...
-3a +30b
Terms
In a simplified polynomial expressed as a sum of products, each of the products is a "term." This expression has two terms:
The sign separating terms in the sum is generally considered to be part of the following term. If this were written 30b -3a, one of the terms would still be -3a.
Coefficient
If each variable value is set to 1 in a term of a polynomial expression, the resulting value is the coefficient of that term. In general, this will be the numerical multiplier of the variables.
30b = 30(1) = 30 . . . . . when b=1
The coefficient of the second term is 30.
