please mark as brainliest!!!

thanks!

Step-by-step explanation:

to add algebraic expressions, we have to add only the like terms.

now, we shall simplify the terms.

• (2m + 3n)sq. = 2m sq + 3n sq = 4m + 9n
• (2m - 3n) x (2m + 3n) = (2m x 2m) + (3n x -3n) = 4m + (-9n) = 4m - 9n

so, we can rewrite it as this:

(4m - 9n) + (4m + 9n)

= + 8m + 0    = 8m

Answer 2

Step-by-step explanation:

(2m-3n)(2m+3n)+(2m+3n) Whole square

= (2m-3n) whole square+(2m+3n)whole square

= 4m square - 9n square +4m square +9n square

4m square + 4m square+9m square -9m square

8m square+0

8m square
