The process is:
C = 2nr
2nr = c
r (2n) = c

That's the answer☝️☝️☝️☝️
or maybe this one
r = 2n + c
sorry, I'm unsure, it has been too long since I studied that...

Answer:
2
Step-by-step explanation:
What you could do is fill in 2 for the equation and y would equal -3 so for the first one it's like
y= 2^2 + 5(2) -17
y= 4 + 10 - 17 which turns into y= -3
In the second y it would be something like
y= 2 - 5 which would equal y= -3
so x=2
If its a right-angled triangle you can find the third side if the length of the other 2 sides are known. Use the Pythagoras theorem.
If you have 2 triangles which are similar and you know the length of one or more sides of one of them then you can find the lengths of corresponding sides in the second triangle.
Answer:
Step-by-step explanation:
sticker price of 6100
390 a month for 24 months....means he paid (390 * 24) = 9360
