Question

The expression -30 + 9k and -3( 10 + 3k ____ equivalent? plzzzzz help

Answer 1

18k

Explanation:

To solve this, you must first multiply -3 by (10+3k). This leaves you with -30-9k. Next, compare which values you need to make the two equations equal. -30=-30, but -9k does not equal 9k. So, you need to add 18k to make the equations equal.
