The prime number is 53 because the others have factors other than itself and 1 but 53 doesn't
Answer:
n = {-1, 7}
Step-by-step explanation:
8n² - 56 = 48n
Subtract 48n from both sides
8n² - 48n - 56 = 0
Divide both sides by 8
n² - 6n - 7 = 0
Factor
alternately use the quadratic equation or complete the square
(n - 7)(n + 1) = 0
n = {-1, 7}
Okay, first thing first... you are amazing
second, number 7 is 5/2
number 10 is 3/6
hope this helps and have a w-o-n-d-e-r-f-u-l d-a-y :)
