Step-by-step explanation:
1. 4x + 8x + 5x + x
=(4+8+5+1)x
= 18x
2. (5a-7b+4)+(5a+2b+3)
= 5a + 5a -7b + 2b + 4 + 3
= 10a - 5b +7
3. (2x³+13x²+6x)+(2x³+5x²+5x)
=2x³+2x³+13x²+5x²+6x+5x
=4x³18x²+11x
4. (-4k^4 + 3k² +14)+(-3k^4-9k+7)
-4k^4 -3k^4 + 3k² -9k + 14 + 7
=7k^4+3k²-9k+21
5. (12m²n+7mn²+2)+(6m²n-4mn²+3mn+13)
=12m²n + 6m²n + 7mn² -4mn² + 3mn + 2 + 13
=18m²n +3mn²+ 3mn + 15
