Answer:

8 terms

The like terms are{ -10a, 15a, a} and -{ 9n, 3n}

The terms of an expression are numbers and variables that constitute it. For example, the simple expression 2x + 1 contains two terms 2x and 1.

Keeping the above definition in mind, we count and find that our expression contains 8 terms.

Like terms of an expression are terms that have same variables and exponents. As an example, 2x^3+ x^3 + y, the like terms are 2x^3 and x^3.

In our case, the like terms are -10a, 15a, and a. The other like terms are -9a and 3n,
