-11 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0

Okay so on this number line that I made you see -3 degrees F and -11 degrees F. All you have to do is count, start at -3 and count the numbers until you get -11 so the answer would be -8 degrees F because it takes 8 units to get to 7 on the negative number line.

Select the correct answer. Rewrite the expression x^3+10x^2+13x+39/x^2+2x+1 in the form q(x)+r(x)/b(x).

daser333 [38]

1 step: Divide the polynomial $x^3+10x^2+13x+39$ by the polynomial $x^2+2x+1$ with remainder:

$x^3+10x^2+13x+39=(x^2+2x+1)(x+8)+(-4x+31).$

Here $x+8$ is quotient and $-4x+31$ is remainder.

2 step: Substitute previous result into the fraction:

$\dfrac{x^3+10x^2+13x+39}{x^2+2x+1}=\dfrac{(x^2+2x+1)(x+8)+(-4x+31)}{x^2+2x+1}=\\ \\=\dfrac{(x^2+2x+1)(x+8)}{x^2+2x+1}+\dfrac{-4x+31}{x^2+2x+1}=(x+8)+\dfrac{-4x+31}{x^2+2x+1}.$
