KC= 31-10= 21
21÷2=10.5
KN= 10.5×4=42
42+1=43
KN=43

Answer:

KN = 74

Explanation:

Given: KC= 31 , KC = 2x + 10 and CN = 4x + 1

We have to find the KN.

Since, KC = 31

also KC = 2x + 10

Comparing both we get,

31 = 2x + 10

2x = 21


x=(21)/(2)

Also, CN = 4x + 1 =
4((21)/(2))+1=43

Thus, KN = KC + CN

KN = 31 + 43 = 74

Thus, KN = 74
