I hope this helps !!
Answer:
4 and 5
Step-by-step explanation:
Assuming your 2nd sentence should be: "The sum of the squares of the two numbers is 41"
X + Y = 9 {equation 1}
X² + Y² = 41 {equation 2}
from equation 1: y = 9-x
Substitute that into equation 2
x² + (9-x)² = 41
x² + 81 - 18x + x²= 41
2x² - 18x + 40 = 0
We can factor out a 2
x² - 9x + 20 = 0
(x-5)(x-4) = 0
x = 5 or 4
checking
Your two numbers are 4 and 5
4² + 5²
= 16 + 25
= 41

Answer:

Step-by-step explanation:
The given equation is :
N=S(P-V)-F ...(1)
We need to solve the above equation for S.
Adding F both sides in equation (1)
N+F=S(P-V)-F+F
N+F=S(P-V)
Dividing both sides by (P-V). So,

So, the above is the expression for S.
