## anonymous one year ago How would we solve this? Steps 2(m − 4) + 1? I need accurate steps and explanations please

1. pooja195

2(m − 4) + 1 First distribute the 2 2 x m=? 2 x -4=?

2. anonymous

@pooja195 can you tell me what is the first step

3. pooja195

I did.

4. anonymous

What do you mean by distribute the 2

5. pooja195

6. pooja195

We need to use the distributive property

7. anonymous

That picture just confused me even more

8. pooja195

Its just an example

9. anonymous

where did another blue come from

10. pooja195

When you distribute the basically multiply the number outside of the parentheses by the numbers inside of the parentheses understood or confused?

11. anonymous

Sort of understood, can you give me an easy example please

12. anonymous

Sort of understood, can you give me an easy example please

14. anonymous

Ok so you move the x to the 5 and multiply

15. anonymous

Can you give me an easy one so I can solve it myself

16. pooja195

17. anonymous

2m. 8?

18. pooja195

Almost correct! :D its 2m-8+1 Now combine like terms :)

19. anonymous

Why would it be +1 it says -1 there

20. pooja195

-8 + 1 =?

21. anonymous

-7?

22. pooja195

yes so we have 2m-7 <---final answer

23. anonymous

Ok

24. anonymous

Im gonna do the first one again

25. anonymous

2(m − 4) + 1?

26. anonymous

So first we bring the m to the 2 so 2mx4+1

27. anonymous

but how do we do the second part, − 4) + 1

28. anonymous

@pooja195

29. pooja195

Not quite we need to MULTIPLY

30. anonymous

− 4) + 1 but how will we multiply

31. pooja195

|dw:1439222259894:dw|

32. anonymous

im stumpted on inequalities and these expressions

33. pooja195

Try again dont give up! :)

34. anonymous

4 x 2 = 8

35. pooja195

*-4

36. anonymous

Oh then -4 x 1

37. pooja195

Where are you getting the 1 from?

38. anonymous

-1

39. anonymous

in the end of the expression

40. pooja195

ignore that for right now

41. anonymous

Ok so what do I multiply then

42. pooja195

Distribute: =(2)(m)+(2)(−4)+1 =2m+−8+1 Combine Like Terms: =2m+−8+1 =(2m)+(−8+1) =2m+−7

43. anonymous

man all those symbols and numbers

44. anonymous

im so bad at this

45. anonymous

im gonna fail flvs

46. anonymous

it just doesnt make sense to me no matter how much I try to understand

47. pooja195

no you wont! im not gonna let u! ok Distribute $\huge~\rm~(2)(m)+(2)(−4)$ Do you understand this?

48. anonymous

i understand 2m because we bring the m to the 2 (is that distributing)

49. anonymous

and the +

50. pooja195

Good -4 comes from the minus sign

51. pooja195

therefore it is a negative 4

52. anonymous

yes so what do we do with the -4

53. pooja195

ok Distribute $\huge~\rm~(2)(m)+(2)(−4)$

54. pooja195

Now multiply ignore the plus sign for right now

55. anonymous

2 x 2 = 4

56. pooja195

where in the world did u get 2 x 2 from?

57. anonymous

umm you said get rid of the +

58. anonymous

then its 2m + 2

59. pooja195

2 x m= ? 2 x -4 =?

60. anonymous

yeah but we dont know what 2xm is

61. pooja195

correct it remains 2m

62. anonymous

yes so 2m x 2

63. pooja195

No 2m -8 2 times -4 = -8
