Write a polynomial that represents the area of the square.
Anika [276]

Answer: x^2+8x+16

Step-by-step explanation:

It is important to remember that the formula for calculate the area of a square is:

A=s^2

Where "s" is the side lenght of the square.

From the figure you can identify that the side lenght of the square can be represented with this expression:

x+4

Therefore, the following expression represents the area of the square:

(x+4)^2

In order to simplify it, you need to remember that:

(a\±b)^2=a^2\±2ab+b^2

Then, you get that the polynomial that represents the area of the given square, is:

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