Explain how you would find the least impossible number of rows in the auditorium

1 answer:

4 0

You would find the least possible rows in the auditorium by multiplying 8 by 70 and the answer would be 560 seats in the auditoturim. This would be correct because Kayla knows that there are at least 70 rows (the least amount of rows).

I hope this helped you

Answer:

$\large\boxed{\dfrac{1}{x^2}+x^2=23}$

Step-by-step explanation:

$\left(\dfrac{1}{x}+x\right)^2=25\qquad\text{use}\ (a+b)^2=a^2+2ab+b^2\\\\\left(\dfrac{1}{x}\right)^2+2(x\!\!\!\!\diagup)\left(\dfrac{1}{x\!\!\!\!\diagup}\right)+x^2=25\\\\\dfrac{1}{x^2}+2+x^2=25\qquad\text{subtract 2 from both sides}\\\\\dfrac{1}{x^2}+x^2=23$
