Answer:
11x + 4
Step-by-step explanation:
First find 2 to the power of 2. Which is multiplying 2 by its self so 4x.
Then add the 4x to 7x which is 11x
Then since 4 doent have an x it cant be combined so thats the answer: 11x + 4
-3 because you could eliminate the 3x by subtracting it by 3x
The answer 309
You jus literally divide 927/3 and get 309
