x2 + 8x + 16 ( And I am from the USA, just so you know, lol) If u can help me with this, plz do so. Thanks and have a great day! Stay safe!

Answer 1

Answer:

Formula to find square area :- side × side

Here, sides = x+ 4

So,

( x + 4 ) ( x + 4)

= x( x + 4) 4 ( x + 4)

= x2 + 4x + 4x + 16

= x2 + 8x + 16

Hence, Option D

Answer 2

Step-by-step explanation:

Formula to find square area :- side × side

Here, sides = x+ 4

So,

( x + 4 ) ( x + 4)

= x( x + 4) 4 ( x + 4)

= x2 + 4x + 4x + 16

= x2 + 8x + 16

Therefore , Option D
