Answer:
2x + 5
Step-by-step explanation:
Make sure you remember the area of a square with side which is [tex]s^{2}[/tex]. Once you figure that out, you need to find the length of a side, make sure you factor the expression of the area as a perfect-square trinomial.
An example of that is...
[tex]a^{2} +2ab+b^{2}[/tex] [tex]= (a +b)^{2}[/tex]
^^key point^^
Break it down and take the length out of the Square of Sum and you should get your answer.
Example: Use Square of Sum and get [tex](2x+5)^{2}[/tex] then, get rid of parentheses >> 2x + 5 and you should get your answer :)
