Question

1. 12x + x =
2. 5y - 10y + 13y =
3. 17a² + 3a + 11a =
4. 6pq + 5p² - 8pq - p² + pq =
5. 8(a + 2b) - 12(2a - pq)

Answer 1

1) 12x+x= 13x
2) 5y-10y+13y
=(5-10+13)y
=8y
3) 17a^2 +3a+11a
= 17a^2 +(3+11)a
=17a^2 + 14a
4) 6pq + 5p^2 - 8pq - p^2 + pq
= (5p^2 - p^2) + (6pq - 8pq + pq)
= 4p^2 - pq

ps: yang nomer 5 gatau, dan dicek lagi yaa takutnya ada yang salah

Answer 2

1. = 13x
2. = 8y
3. = 17a^2 + 14a
4. = 4p^2 - pq
5.) 8a + 16b - 24a + 12pq = 16b - 16a + 12pq
