13. Not a monomial, the exponent of one of the variables is not a nonnegative interger.

16.3, degree is 2

19. Yes,0

22. Yes ,0

26. Yes ,2

29.(x^3-2x^2+5x+10)-2x^2+4x-3 = x^3-4x^2+9x+7

31. (6x^5+x^3+x)+ 5x^4-x^3+3x^2 = 6x^5+5x^4+3x^2+x

33.(x^2-3x+1) +6x^2+2x-8 = 7x^2-x-7

36. 32x^2-24x-8 - (24x^2-46x+12) = 8x^2+22x-18

40.8-8y^3 + (4+4y+4y^2+4y^3) =8+4y+4y^2-4y^3

44.15x^4-20x^3

46.2x^3+2x^2+2x-3x^2-3x-3= 2x^3-x^2-x-3

49.2x^2+9x+10

52. X^22x-8

55.2x^2-x-6

58.-3x^2-4x-1

60.2x^2-3x-9

63.-6x^2-13xy-6y^2

66. X^2-1 =x^2+1 or x^2-1

69.x^2+4x+16= (x+4)^2

70. X^2+10x+25= (x+5)^2

73.(3x+4) or (3x-4)

76. (3x-4)^2

79. (3x+y) or (3x-y)

82. (x-y)^2

84.(2x+3y)^2

87.8x^3+4x^2+2x+1

94. 5x^2+x

97. -2x^2+x+1

102.x^2-a^2

105.because it is like two negative number make positive its just a rule

108. Horizonatal way because you are putting number under each other"
