Question

30v^4w^3 - 12v^4w^3 = ???
HELP?

Answer 1

\[(30v^{4}w ^{3})-(12v ^{4}w ^{3})\]

Answer 2

Is that you equation?

Answer 3

Yes

Answer 4

17v^4w^3 should be the answer i believe

Answer 5

No...that not it

Answer 6

I need help with how to do it, not the answer

Answer 7

yeah ok pretty easy ill explain it

Answer 8

Kay, i just got confused.

Answer 9

I can do this one :)

Answer 10

You have:
\[(30v^4w^3)-(12v^4w^3)\]
Pick a letter, let's say \(a\) for amber haha
Let \(a=v^4w^3\)
So then you can simplify:
\[(30v^4w^3)-(12v^4w^3)=30a-12a=18a\]
And we can substitute back:
\[18a=18v^4w^3\]

Answer 11

\[(30v ^{4}w ^{3}-12v ^{4}-w ^{3})\]

Answer 12

See how its a negative 12v^4 and negative w^3 bceause you multyply the -(12v^4W^3)

Answer 13

Reaper,
\[-12v^4w^3\neq-12v^4-w^3\]...

Answer 14

ohh shoot my bad yes your right i was thining smth else

Answer 15

I was told to just line them up vertically and subtract by my teacher

Answer 16

If you had \(-(12v^4+w^3)\), then you'd be correct :)

Answer 17

yeah keith is right

Answer 18

that works to amber

Answer 19

Ohh you could do that too!
Like so:
