multiples space of space 3. space So space the space factors space can space be space 1 comma 5 comma 7 comma 35.
If space straight m equals 1 space then space 3 straight m plus 2 space is space 5.
If space straight m equals 11 space then space 3 straight m plus 2 space is space 35.
Hence space only space 5 space and space 35 space are space of space the space form space 3 straight m plus 2. space Their space sum space is space 40. end style
