Forty five thousand nine hundred twenty
Answer:
1440
Step-by-step explanation:
Let's say x = number of hours worked per week for 12 people. Now one worker works 30 hours a week so if you multiply 12 workers by 30 you will get how many hours 12 workers worked. so x = 12 • 30. 12 • 30 is 360. so x = 360 or for 1 week 12 workers worked 360 hours. now we need to find the amount of hours for 4 weeks. so we can do 4x or 4 times the amount of hours per one week. since x = 360. 4 • 360 = 1440.
See the suggested solution in the attachment.

Alright now combine all like terms remember no matter what you can allways add like terms ok now it would be 5-3 you should get two now add the n and the squared 2 and 2n2 should be your answer witch is A
Now for the other equation 8+-4 =4 3b +6b = 9b now drag the 2c down and you get
4+9b-2c I hope this helps you
