It is: 38+4 = 42
4m + 9 + 5m - 5 = 42 9m + 4 = 42 9m = 38 m = 38/9
42 metres 65 centimetres + 38 centimetres = 43 metres 3 centimetres.
-3 + 4 - 6 + 3 - 2 + 42 = 1 - 6 + 3 - 2 + 42 = - 5 + 3 - 2 + 42 = - 2 - 2 + 42 = - 4 + 42 = 38
18+24+16+22 42+38 =80
38 and 42 is 80 stamps. Twice 80 is 160 minus 8 is 152 38 plus 42 plus 152 is 232.

The LCM of 38 and 42 is: 798
The factors of 42 are 1, 2, 3, 6, 7, 14, 21 and 42. The factors of 38 are 1, 2, 19 and 38. 2 is the greatest factor which divides both 38 and 42. So, the GCF of 42 and 38 is 2.
x2 + 13x + 4 = (x + 6½ + √38¼)(x + 6½ - √38¼). To find this, we need to find p and q, where p + q = 13, pq = 4. 4 = 42¼ - 38¼ = (6½ + √38¼)(6½ - √38¼); thus, p = (6½ + √38¼), q = (6½ - √38¼).
Factors of 38: 1, 2, 19, 38. Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42. GCF (38, 42) = 2
