Question

Anna has a square shaped cardboard of surface (x2 + 12x + 36) cm2. Find the side of the cardboard

Answer 1

Answer:

Step-by-step explanation:

A square surface is determined by the product of its sides

         s = L ^ 2

Thus, the surface of the cardboard of side C, will be

              x ^ 2 + 12x + 36 = C ^ 2

Factoring

              (x + 6) (x + 6) = C ^ 2

THE SIDE IS (x + 6)

Answer 2

Answer:

$\boxed{(x+6)}$

Step-by-step explanation:

The surface of a square is $\sf side^2$.

$s^2 =x^2 +12x+36$

Take the square root on both sides.

$s=\± \sqrt{x^2+12x+36}$

$s=\± (x+6)$

The side of the cardboard cannot be a negative value.
