1. andriod09

2(x+y) and 2(x+y), don't know if you put it twice on accident or a part of the acuall questin.

2. dmezzullo

so is tht what the answer is? for both

3. andriod09

is it supposed to be twice or not?

4. dmezzullo

no just once

5. andriod09

6. dmezzullo

i got that...then i have 2x+y

7. andriod09

no, then it would be like this: \[2(x+y)\] you would do the parenthesis first: \[2(xy)\] then you would multiply them, thus the final answer is:\[(2xy)\]

8. dmezzullo

so 2(x+y) for the first part and then (2xy) for the second part?

9. andriod09

yes. that would work i was showing you how to accually solve something like this.

10. dmezzullo

k... then what would i do for the complete sentences?

11. dmezzullo

?

12. andriod09

okay, so i reread the questinon, the first one, like you said was 2xy, while twice the sum of x and y would be:2(x)+2(y)=4xy i think...
