If x = 4, you would replace the “x”s with 4’s! So the problem would work out to be 4^2 - 4 over 4 - 8. 4^2 = 16. You would then subtract. 16 - 4 = 12. Now your problem is 12 over 4 - 8. 4 - 8 = -4. Now your problem is 12 over -4. So now you just divide. 12 / -4 = -3! -3 should be your answer! If you need me to write it out to show you I’d be happy to! Hope this helps! :)

C) This study may not portray cell phone use correlation over a large population efficiently because of the sample size and the predetermined conclusion that cell phone use causes cancer.
