in stepwise answer​

Answer 1

Answer:

18xy-3x+10

Step-by-step explanation:

so what you wanna do is take off all of the parenthesis

and you will have...

2x+5y×3x+7y-5x+3y×x+3y

so now you want to combine like terms

and get

18xy, 3x, and 10

so now you want to add the adding and subtracting tools

and get..

18xy-3x+10

and thats your answer.

Hope this helps
