Answer:
1) 45a + 52 + c - 12a
= 45a - 12a + c + 52
= 33a + c + 52
2) (4n² + 3) + (10m² + 9)
= 10m² + 4n² + 3 + 9
= 10m² + 4n² + 12
3) (-18+ab) + (7ab+10)
= 7ab + ab + 10 - 18
= 8ab - 8
4) 3x²- 11 x 12 + 18x² + 20 x 100
= 3x² - 132 + 18x² + 200
= 21x² + 68
If this is the correct question:
3x²- 11x + 12 + 18x²+20x + 100
= 3x² + 18x² + 20x - 11x + 12 + 100
= 21x² - 9x + 112
5) (12x³ + 3 + 4) + (15³x + 4x² + 10x - 10)
= 12x³ + 7 + 3375x + 4x² + 10x - 10
= 12x³ + 4x² + 3385x - 3
If this is the correct question:
(12x³ + 3x + 4) + (15x³ + 4x² + 10x - 10)
= 12x³ + 15x³ + 4x² + 3x + 10x + 4 - 10
= 27x³ + 4x² + 13x - 6
Encode the questions correctly next time.
