Answer:

D: 5(9a-2b)

Step-by-step explanation:

Each expression in the choices is factored, so we need to see how to factor the given expression.

To factor the given expression, you need to factor out the greatest common factor of both terms.

The terms are 45a and -10b.

The GCF of 45 and -10 is 5.

The GCF of a and b is 1. There is no common factor other than 1.

The GCF of the 2 terms is 5, so we factor out a 5.

45a - 10b = 5(9a - 2b)

Answer: D: 5(9a-2b)
