Answer 1

Which expression is equivalent to x + y + x + y + 3(y + 5)? 2x + 5y + 5 2x + y + 30 2x + 5y + 15 2x + 3y + 10 

$x + y + x + y + 3(y + 5)= \\ \\ x+y+x+y+3y+15= \boxed{ 2x+5y+15 }$

Answer 2

Answer:

Option 3 - $x+y+x+y+3(y + 5)=2x+5y+15$

Step-by-step explanation:

Given : Expression $x + y + x + y + 3(y + 5)$

To find : Which expression is equivalent to given expression ?

Solution :

Expression $x + y + x + y + 3(y + 5)$

Open the bracket,

$x + y + x + y + 3y +15$

Add like terms,

$2x+5y+15$

Therefore, $x + y + x + y + 3(y + 5)=2x+5y+15$

So, option 3 is correct.
