SOMEONE PLEASE JUST ANSWER THIS FOR BRAINLIEST!!!

Answer:

$y^2 + 8y + 16$

Step-by-step explanation:

$(6y^2 + 2y + 5) - (5y^2 - 6y - 11) =$

The first set of parentheses is unnecessary, so it can just be removed.

$= 6y^2 + 2y + 5 - (5y^2 - 6y - 11)$

To remove the second set of parentheses, you must distribute the negative sign that is to its left. It changes every sign inside the parentheses.

$= 6y^2 + 2y + 5 - 5y^2 + 6y + 11$

Now you combine like terms.

$= 6y^2 - 5y^2 + 2y + 6y + 5 + 11$

$= y^2 + 8y + 16$

Can someone please help me? i hope you can see this omg

Gemiola [76]

Step-by-step explanation:

length = (2x + 3) units

width = (x - 7) units

Area = 2( length × width)

Area = 2( (2x + 3) × (x - 7) )

Area = 2( 2x² - 14x + 3x - 21)

Area = 2 ( 2x² -11x - 21)

Area = 4x² - 22x - 42
