Answer:
Step-by-step explanation:
d ko po alam yong no.4 at 5
1.) The answer is -2x
SOLUTION:
→ 2x + 3x + (-7x)
→ 2x + 3x - 7x
→ 5x - 7x
= -2x
2.) The answer is 14xy
SOLUTION:
→ (-8xy) + 10xy + 12xy
→ -8xy + 10xy + 12xy
→ -8xy + 22xy
= 14xy
3.) The answer is 0
SOLUTION:
→ 4a + 3a + (-2a) + (-5a)
→ 4a + 3a - (2a - 5a)
→ 7a - 7a
= 0
4.) The answer is 6qrs
SOLUTION:
→ 3qrs + 4qrs + (-qrs)
→ 3qrs + 4qrs - qrs
→ 7qrs - qrs
= 6qrs
5.) (Is it – m² + 7m² + (-3m²) + 10m²? If so..) The answer is 15m²
SOLUTION:
→ m² + 7m² - 3m² + 10m²
→ 18m² - 3m²
= 15m²
