1. triciaal

do you have an example of what you need help with?

2. fantasywolfpack

yes

3. fantasywolfpack

@triciaal yes i do

4. fantasywolfpack

Which algebraic expression is equivalent to the expression below? 9(4x + 8) - 6 36x + 18 36x + 72 36x + 2 36x + 66

5. fantasywolfpack

@dan815

@DullJackel09

9. Mehek14

do you know how to distribute?

10. fantasywolfpack

no

11. fantasywolfpack

Which algebraic expression is equivalent to the expression below? 9(4x + 8) - 6 36x + 18 36x + 72 36x + 2 36x + 66

12. Mehek14

$$\bf{a(b+c)=a*b+a*c}$$

13. fantasywolfpack

what

14. Mehek14

so you would do the same with 9(4x + 8) $$\bf{9*4x=36x\\9*8=72\\36x+72}$$

15. muscrat123

so u take the 9 first

16. Mehek14

multiply whatever is outside of the parenthesis to whatever is inside the parenthesis

17. muscrat123

then u multiply it by each individual # in the ()S

18. fantasywolfpack

um ?

19. Mehek14

so now that I have distributed: 9(4x + 8) $$\bf{9*4x=36x\\9*8=72\\36x+72}$$ you have $$\bf{36x+72-6\\72-6=?}$$

20. fantasywolfpack

6(9x + 8) + 7(11 - x) but this

21. muscrat123

|dw:1444260532381:dw|

22. fantasywolfpack

wtf

23. muscrat123

sorry its messy. OS is laggikng

24. muscrat123

lagging*

25. Mehek14

|dw:1444260598129:dw|

26. muscrat123

thanks!!!!

27. Mehek14

now you would subtract 72-6

28. muscrat123

Os is really lagging for me

29. fantasywolfpack

but what about this Which algebraic expression is equivalent to the expression below? 6(9x + 8) + 7(11 - x) 47x + 29 47x - 125 47x + 125 61x + 125

30. fantasywolfpack

i'm confuse

31. Mehek14

distribute again

32. muscrat123

do the same thing

33. fantasywolfpack

but there a +7

34. fantasywolfpack

do ii time seven

35. muscrat123

yes

36. Mehek14

|dw:1444260748145:dw|

37. triciaal

to distribute you multiply what is in front of the parenthesis by each term inside

38. fantasywolfpack

what

39. fantasywolfpack

is there an easyer way to explan it

40. triciaal

follow what @Mehek14 did above

41. fantasywolfpack

i confuse about this part

42. Mehek14

$$\bf{a(b+c)=a*b+a*c}$$

43. triciaal

the 6 is in front and outside inside you have 9x + 8 so you do 6 times 9x + 6 times 8

44. fantasywolfpack

ok but this 5(4x + 3) + 5x

45. triciaal

so you do the same process just different numbers

46. fantasywolfpack

but + 5x

47. triciaal

|dw:1444261108473:dw|

48. triciaal

now group like terms to simplify

49. fantasywolfpack

? simplify

50. triciaal

|dw:1444261274972:dw|

51. fantasywolfpack

so like 1+1 then simpplify is 2

52. triciaal

|dw:1444261311211:dw|

53. fantasywolfpack

what about the if it time and addion witch would u do

54. triciaal

not sure what you are asking

55. triciaal

give an example

56. fantasywolfpack

7(x - 1) + 12(x + 14)

57. triciaal

take your time and apply the same process

58. fantasywolfpack

12*x=12x

59. fantasywolfpack

then 12*14=144

60. fantasywolfpack

then 7*x=7x

61. triciaal

|dw:1444261600620:dw|

62. fantasywolfpack

7x*1=7

63. fantasywolfpack

is that how

64. triciaal

yes review what I have 12*14 = 168 7*-1 = -7

65. fantasywolfpack

ohhhhh

66. fantasywolfpack

i metal u and fan

67. triciaal

thanks

68. fantasywolfpack

ur welcome

69. triciaal

keep practicing start from left to right group like terms to simplify

70. triciaal

|dw:1444262092004:dw|

71. fantasywolfpack

(9 + 9x) - 9x

72. fantasywolfpack

does 9x go back ward

73. triciaal

|dw:1444262420703:dw|

74. fantasywolfpack

oh so go in order

75. triciaal

yes left to right

76. fantasywolfpack

thank u

77. triciaal

when there is no number in front of the parenthesis it means 1

78. triciaal

when you have a minus sign then it is -1 remember a negative times a negative is positive opposite signs gives negative
