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:
(1 + 3x).
Step-by-step explanation:
We have to evaluate the missing term within the brackets in the following equation.
The equation is, 5 + 15x = 5(?)
Now, 5 + 15x
= 5 × 1 + 5 × 3x {We have to factorize the term where 5 is a factor}
= 5(1 + 3x) {This is reverse of the distributive property of multiplication}
Therefore, the missing term within the brackets is (1 + 3x). (Answer)
3x-2x^2+7-3x^2
=3x-2x^2-3x^2+7
=3x-5x^2+7
=-5x^2+3x+7 that’s how it’s solved and that’s the answer as well. Come back for help
Undefined means it goes through the x intercept, x=3
