Question

please someone help me

Answer 1

Distribute 4(3x - 5) + 6

Answer 2

your job is to take \[3(4x-5)+6\] , distribute, and then combine like terms

Answer 3

first step is what @ShadowLegendX said

Answer 4

do you know what he/she is talking about "distribute"
it means multiply both terms inside the parentheses by 4

Answer 5

actually i wrote it wrong, it is \[4(3x-5)+6\]

Answer 6

you got that or no?

Answer 7

no

Answer 8

ok lets go slow

Answer 9

what is \(4\times 3x\)?

Answer 10

12

Answer 11

yes, \(4\times 3=12\) but what about the \(x\)?

Answer 12

what do you mean?

Answer 13

where did it go?

Answer 14

\[4\times 3x=?\] the \(x\) should be in your answer

Answer 15

waht to you mean the x should be in my answer

Answer 16

\[4\times 3\diamondsuit =12\diamondsuit\]\[4\times 3x=?\]

Answer 17

12

Answer 18

its 12?

Answer 19

no, it is not 12, it is \(12x\)

Answer 20

oh

Answer 21

that is why i asked where the \(x\) went

Answer 22

now how about \(4\times (-5)\)?

Answer 23

19

Answer 24

no, not 19

Answer 25

i got 19

Answer 26

how did you get it? \[4\times(-5)\] contains one minus sign, for we know the answer is negative, not positive

Answer 27

what? but how you said t has a minus sighn how is it negitiv if it has a minus sighn?

Answer 28

i am not sure how to answer that
is \(-50\) positive or negative?

Answer 29

positiv

Answer 30

you said its a minus sighn so its minus 50

Answer 31

wich is 0

Answer 32

im sory if i sound stupid :(

Answer 33

minus fifty is not zero
it if is minus fifty degrees, it is much colder than 0 degrees

Answer 34

if a number has a minus sign in front of it, it is negative

Answer 35

and when you multiply two numbers together, if one of them is negative (has a minus sign in front) then the answer is negative as well (has a minus sign in front)

Answer 36

so for example \[2\times (-4)=-8\] since \(2\times 4=8\) and there is one minus sign there

Answer 37

so now lets try again
we have to compute \(4\times (-5)\)

Answer 38

-1?

Answer 39

hmm i think what you mean is that \(4-5=-1\) right?
what is \(4\times 5\)? forget about the minus sign for a second

Answer 40

ok

Answer 41

so \[4\times 5=?\]

Answer 42

20?

Answer 43

yay

Answer 44

that makes \[4\times (-5)=-20\]

Answer 45

now we have distributed the 4 in \(4(3x-5)\) by multiplying each term by 4 to get \[4(3x-5)=12x-20\]

Answer 46

we actually have \[4(3x-5)+6\] so now that is \[12x-20+6\]
what is \(-20+6\)?

Answer 47

wait 12 - 20 is 12 and 20+6 is 26

Answer 48

there is no 12 there, that is, there is not term that is just 12
there is a \(12x\) which does not combine with the two numbers
the two numbers are \(-20\) and \(+6\)

Answer 49

but you said 12 - 20

Answer 50

so the question is now, what is \(-20+6\) or if you prefer \(6-20\)

Answer 51

where do you see \(12-20\)?

Answer 52

ahh yes it does say \[\huge 12\color{red}x-20+6\]

Answer 53

the \(\color{red}x\) is a variable, it is not the number 12

Answer 54

\[\huge 12\color{red}x\overbrace{-20+6}^{\text{combine these two numbers}}\]

Answer 55

26?

Answer 56

and if x is a varibalbe then why did you put hte 12 there?

Answer 57

no \(20+6=26\) but you have \(-20+6\)

Answer 58

the 12 was because \(4\times 3x=12x\)

Answer 59

oh

Answer 60

so now we are back to "what is \(-20+6\)?

Answer 61

btw the number in front of the variable is called the "coefficient"
\(12x\) means \(12\times x\) you just don't write the \(\times \) symbol
for example of \(x\) was $100 then \(12x\) would be $1200

Answer 62

oh

Answer 63

ok so finally what is minus twenty plus six?

Answer 64

-26

Answer 65

nope
if you spent twenty dollars, and then got a 6 dollar rebate, how much would you really have spent?

Answer 66

i dont know what rebate means

Answer 67

got $6 back

Answer 68

oh

Answer 69

26

Answer 70

do you know the rules for adding "signed numbers"?

Answer 71

like \(-10+3\) or \(-5-4\) or \(12-18\)?

Answer 72

no

Answer 73

then you cannot do a problem like this
you need to be able do add and subtract before algebra, also know the distributive property, and what a variable is
this kind of question should come after you learn those things
i can tell you briefly what the rules are, but it takes quite a bit of practice to understand them and know how to use them quickly

Answer 74

distribute and combine like terms :)

Answer 75

the problem here is that when we finally distribute and combine like terms, you are going to have to do it four more times, for each of your possible answers
then see which ones give you the same thing

Answer 76

@Alknowsall yes, we have been doing that for a while now, and have not gotten their yet

Answer 77

@MariahDimond i am not being critical, i am only saying that it is impossible to do algebra without knowing the basics of arithmetic
if that is still not clear, work on that first

Answer 78

true hahaha @satellite73

Answer 79

yeah but we are stuck at the addition step here \(-20+6\)

Answer 80

lol oops
you can flip it and do 6-20= ? if that helps

Answer 81

@MariahDimond 6-20=? :P

Answer 82

what do you mean

Answer 83

6 minus 20 =?

Answer 84

I took what @satellite73 wrote -20+6 and flipped it to make 6-20 both have the same answer

Answer 85

-26? minus is negitiv isent it?

Answer 86

wait does this mean im stupid

Answer 87

Ok let's try using a number line

Answer 88

Basically you count up from -20 so count 6 spaces up what number are you at?

Answer 89

yea

Answer 90

What number do you get?
