17a + 21a + 45 = 38a+ 45
21a - 6a
3(7a - 5b) + 2(4a - 3b) Multiply the contents of each bracket by the number outside it: 21a - 15b + 8a - 6b Bring like terms together: 21a + 8a - 15b - 6b Combine like terms: 29a - 21b This cannot be simplified further.
The "Bobcat" name was before the numerical assignment. They are one in the same gun.
12a + 6b + 9a + 14b =(12a + 9a) + (6b + 14b) =21a + 20b
