2y+2x+8y would equal 12xy? or 12yx? or whatever else it cud possibly be?

Question

please help me with this question thanks!

Answer 1

2y+2x+8y = 2x+10y = 2(x+5y) ≠ 12xy

new math

2 apples plus 2 pears plus 8 apples equals 10 apples and 2 pears or 2 times (1 apple and 5 pears)

Answer 2

2y+2x+8y=2x+10y
and

see kid
12xy=12yx
proof:-
take x as 3 and y as 4
12 x 3 x 4 = 12 x 4 x3
144=144

Answer 3

neither... You can't add the "y" values to the "x" values, because they are totally different variables. The answer is

10y+2x

but, if you knewwhat y and x were, you could figure out what 2y, 2x, and 8y were equal to, then add them together!

hope that helps!

Answer 4

2y+2x+8y
=2x+2y+8y
=2x+10y
but this is not equal to 12xy.
if the answer is 2xy+10xy (instead 2x+10y), then this is equal to 12xy.
hope now you can understand the difference.

Answer 5

Just combine like terms and the answer is 10y+2x or 2x+10y.

Answer 6

the only answer is

2x+10y

which you get by adding the 'y's together
you can't add the rest together because the 2 and the 10 are being multiplied by the variables, and you don't know what those variables are. since all the multiplication has to be done before addition, you're stuck and that's all you can do.

you could also write it 2(x+5y) to mean the same thing

Answer 7

You can only add like terms,

so 2y+2x+8y=10y+2x

I hope that this helps.

Answer 8

2y+2x+8y = 2x+10y

You can only add up like terms.

Answer 9

2y + 2x + 8y = 10y + 12x

you can only add alike terms.... and if you write xy... that means you're multiplying it

Answer 10

10y + 2x
