a) 2, b) 1, c) 3, d) 4​

Answer 1

Answer:

first be solved equation 2n+13 and n+7

we solved this equation and the HCF of it's answer is 1 .

so,

option b. 1 is your answer.

I hope it's help you

thanks

please mark my brainlist

Answer 2

Answer:

its given that

A= 2n + 13

B = n+ 7

consider n=1 then

A = 2×1+13 = 15

B= 1 +7 = 8

hence the HCF of A and B is 1

similarly you can take any natural number and solve...
