Answer:
(x+8)^2 - 60 = 0
Step-by-step explanation:
x^2 + 16x + 4 = 0
x^2 + 16x + 64 - 60 = 0
(x + 8)^2 - 60 = 0
E/(c^2) = mc^2/(c^2)
m = E/(c^2)
3 is the greatest common denominator
Step-by-step explanation:
Well if you dont understand something ask a teacher for help or study on a topic that you struggle with for example math try looking up different math questions and solving them or ask a teacher is you can have pratice questions or problems then show it to him/her so they can check to see if you are right.
