Answer:
Our constant is the number 12 (as there is to variable to change its meaning)
The coefficient of our second term is 8 (our number preceding the variable denoting how many times this variable will be taken)
There are 4 terms in the expression (in algebra, all variables and numbers are considered to be terms)
The terms we have then are: 5m, -8n, 2p, and -12
Explanation:
Any constant is a number that is not attached to a variable
A number attached to a variable is called the coefficient
All numbers and variables within an algebraic expression are called terms.
Each term in an algebraic expression can be broken down or isolated. In these cases, we must ensure to include any signs.
