Factor.

45c+25d

could someone guide me how to start this? thanks

You mean factorize?

bring out 5 from both sides. It's the highest common factor of both sides:

5(9c+5d)

Factor 35r–30.

To factor the expression 45c + 25d, we need to find the common factors between the terms. In this case, the constants 45 and 25 have a common factor of 5. Additionally, both terms have c and d as variables, which means they have no common factors in terms of variables.

To factor out the common factor of 5, we can rewrite the expression as follows:

5(9c + 5d)

Now, we have factored out the common factor 5 from both terms, resulting in the factored form: 5(9c + 5d).
