thanks!!!

Step-by-step explanation:

14. -52 / 4 = -13

(a negative integer when divided by a positive one gives a negative result.)

15. 56/4 because there are 8 boxes and 56 marbles. the number of marbles in each box will be 56/8 = 7.

16. additive identity

(this is just a fact. no explanation)

17. identity property

18. (-5)+5=0

this is because the sum of a number and its additive inverse is always 0.

19. a(b+c) is NOT equal to a+(b+c)

distributive property is:

a(b+c) = ab+ac

20. (34)(43) is NOT equal to 1

identity property of multiplication states that any number multiplied by 7 is always the number itself.
