Your answer is 3. 3*2= 6 6-7= -1 and if -1 is increased by 2 you get 1. So the mystery number is 3 I hope this helps:)

If a polynomial function f(x) has roots 1+square root of 2 and-3, what must be a factor of f(x)?

nevsk [136]

To find the factor a a polynomial from its roots, we are going to seat each one of the roots equal to $x$ , and then we are going to factor backwards.

We know for our problem that one of the roots of our polynomial is -3, so lets set -3 equal to $x$ and factor backwards:
$x=-3$
$x+3=0$
$(x+3)$ is a factor of our polynomial.

We also know that another root of our polynomial is $1+ \sqrt{2}$ , so lets set $1+ \sqrt{2}$ equal to $x$ and factor backwards:
$x=1+ \sqrt{2}$
$x-1= \sqrt{2}$
$x-1- \sqrt{2}=0$
$(x-(1+ \sqrt{2})=0$
( $(x-(1+ \sqrt{2} ))$ is a factor of our polynomial.

We can conclude that there is no correct answer in your given choices.

The sum of the measures of two complementary angles exceeds the difference of their measures by 72°. Find the measure of the sma

Neporo4naja [7]

First we need to define our conditions. Since the angles are complimentary, the sum of the angles must be equal to 90 degrees.

let x = first angle
y = second angle

x + y = 90

from the second condition in the problem

x + y =72 + x -y
solving for x

x= 54

therefore the shorter side is 90 - 54 = y

y = 36 degree, the shorter side
