Write the word problem in algebraic form:
n2 -14 = 5n
Write as a quadratic:
n2 - 5n - 14 = 0
Factor:
(n+2)(n-7) = 0
Solve:
n+2 = 0 => n = -2
n-7 = 0 => n = 7
positive solution is 7. (14 less than 72 = 35 which is also 5 times 7)
55/20 = 2.75
It costs $2.75 per person
Step-by-step explanation:
55/12 is your answer
please give me some thanks

when we add -12 and 6 we get -6
after that we subtract -6 from -4 to get -10
