finlep [7]

Answer:

The other sides of the square are

8x+12+16+8x,(8x+8x)+(12+16) and 16x+28  

Step-by-step explanation:

Square:

  1. The all sides of a square equal.
  2. The sum of four angles is 360°.
  3. The diagonals bisect each other.
  4. The length of diagonals are equal.

Like terms:

Like terms are terms that have the same variables and the power of the variable also same.

Given the length of the side is

=4(2x+3)+16+8x

=4.2x+4.3+16+8x [ Apply distributive property]

=8x+12+16+8x

=(8x+8x)+(12+16)   [ separating like terms]

=16x+28                [Adding like terms]

The other sides of the square are

8x+12+16+8x,(8x+8x)+(12+16) and 16x+28
