Question

Write a simplified polynomial expression to represent the area of the rectangle below.
2x-4
x+5

Answer 1

Can you combine any 'like-terms' ?

Answer 2

r u asking me to answer that because you know the answer and you want me to answer it or are u asking because you dont know??

Answer 3

I know you can, I'm asking if you know how to combine them.

Answer 4

no i dont

Answer 5

1x+2x =3x, so 2x-4x = ?

Answer 6

6x

Answer 7

but how did you get 1x

Answer 8

i'm just showing you the form
In general: 1x+2x=3x, 5x-3x=2x
In your specific problem 2x-4x = ? (it's not 6x)

Answer 9

idk the answer but i luv ur pic puertoricangirl

Answer 10

@ nicole lol thank

Answer 11

you

Answer 12

if its not 6x then it has to be 8x

Answer 13

2x-4x+5 can be re-written as x(2-4)+5, can you solve this?

Answer 14

3

Answer 15

what is 2-4?

Answer 16

-2

Answer 17

ok

Answer 18

like in my example x(2-4)+5, would yield x(-2)+5

Answer 19

Sorry, so your equation 2x-4x would = -2x

Answer 20

So once you make that combination, what are you left with in your equation?

Answer 21

You started with 2x-4x+5, we just worked the 2x-4x = -2x, so you're left with -2x+5

Answer 22

ok then what...

Answer 23

that's it, -2x+5 is all you do. It asked for a polynomial expression, which means it will have an x in it.

Answer 24

oooooooooooooooooohhhhhhhhhhhhhhhh!!!!!!!!!!!!!!!!!!
