Answer:
Step-by-step explanation:
Linda sold 14
John sold 29 which is 14 two times plus one
29+14=43
X+ (x+2)+ (x+4)= -21
3x+6=-21
3x=-27
x=-9
Final answer: -9, -7, -5
49 is composite because it has factors other than itself and 1, 7 and 7, namely. So you could have one row of 49 books, 49 rows of one book or 7 rows of 7 books.
