Answer:
The answer is 0
Step-by-step explanation:
-57 cancels out 57 making it 0.
-5a^2 - 7a = -a x (5a + 7)

13. 1,6
18. -15,12
19. -7, 1/2
I would would say 7.
Mom + Dad + daughter + daughter + daughter + daughter + plus one brother = 7
Since they are all sisters and it says each one has one brother I think that would mean 7. That's just my comprehension of the question, though I may 100% wrong.
