Simplify: 12 + 9z + 14 + 11

9z+37

Step-by-step explanation:

First, look for like terms. 12, 14, and 11 seem to be like terms (they are all numbers) so that means you can add them up. What is 12+14+11? 12+14+11 is 37. Now, you should be left with the equation 9z+37. Can these two terms be added? No, because z is an unknow variable we don't know. So your final answer should be 9z+37. Hope this helps!
