Answer:

about 7.0710678cm

Step-by-step explanation:

it's a square so the sides are equal.

the diagonal is 100cm

This makes a right triangle with two sides

since the sides are equal, they both are equal to the square root of 50, which is half of 100

the square root of 50 is about 7.0710678cm

Factor the polynomial.

Degger [83]

It is answer choice A because you have to take the the GCF of each number which is 2x. Then if you were to divide the numbers by 2x you would put those numbers in the brackets.
$2x( x^{2} +2x+4)$ because $2x^3/2 x = x^{2}$ and $4 x^{2} /2x = 2x$ and $8x/2x = 4$
