Step-by-step explanation:
Pitagora theorem is 14^2=9^2+x^2
-9^2 -9^2
so the equation is
x^2=14^2-9^2
By solving the quadratic equation using completing the square method we got that Penelope should have added 4 to both sides instead of adding 1.
<h3>What is quadratic equation ?</h3>
Any equation of the form where x is variable and a, b, and c are any real numbers where a ≠ 0 is called quadratic equation .
Given work of Penelope is
Now we can see that Penelope determined the solutions of the quadratic function by completing the square. so he must have been done as following
By solving the quadratic equation using completing the square method we got that Penelope should have added 4 to both sides instead of adding 1.

Total of 6 numbers: 360
1 number: 30
Total of the other 5 numbers: 360 - 30 = 330
The average of the x numbers is the sum of the numer diveded by "x", so:
330 divided by 5 = 66.
The average of the other 5 numbers is 66
