Answer:

It would be option 2.

Step-by-step explanation:

This is because option 1 does not have a irrational number that goes on indefinitely, option three has the square root of 25, which equals 5 meaning it is rational, and the last option also gives us rational choices. Therefore, the only possibility is that it would be option 2.

URGENT !!! 25 POINTS AND BRAINIEST FOR CORRECT ANSWER!!!

Given a polynomial p(x) with leading coefficient $a$ and solutions $x_1,x_2,\ldots,x_n$ , we have

$p(x)=a(x-x_1)(x-x_2)\ldots(x-x_n)$

That's why we have to find the solutions first. We complete the square by adding 3 to both sides:

$x^2-2x-2=0 \iff (x^2-2x-2)+3=3 \iff x^2-2x+1=3 \iff (x-1)^2=3$

From here, we continue by taking the square root of both sides:

$x-1=\pm 3 \iff x=1\pm\sqrt{3}$

So, the two solutions are

$x_1=1+\sqrt{3},\quad x_2=1-\sqrt{3}$

Which yields the factorization

$x^2-2x-2=(x-1-\sqrt{3})(x-1+\sqrt{3})$

A rectangle with an area of 3990 cm2 is x centimeters wide and (x+4) centimeters long. To the nearest tenth of a centimeter, the

Karolina [17]

Answer: width:60.2 cm

Length: 64.2 cm

Step-by-step explanation:

Given

The area of the rectangle is $3990\ cm^2$

Width of the rectangle is $x\ cm$

Length of the rectangle is $x+4\ cm$

Area of the rectangle is the product of length and width

$\therefore 3990=(x+4)x\\\Rightarrow 3990=x^2+4x\\\Rightarrow x^2+4x-3990=0\\\Rightarrow x=60.198\ or\ -65.198\ cm\\\text{Neglecting negative term}\\\Rightarrow x=60.198\approx 60.2\ cm$

Width of the rectangle is $60.2\ cm$

Length of the rectangle is $60.2+4=64.2\ cm$
