Answer:
2x^2+4x-2 = 2 * (x - 1 -
) * (x - 1 + )
Step-by-step explanation:
Factor completely 2x^2+4x-2
2x^2+4x-2 = 2* (x^2 + 2x - 1)
x = 1 + root( 4 - 4*(-1))/2
x = 1 + root(2)
and x = 1 - root(2)
Answer:
10 ft to nearest foot.
Step-by-step explanation:
We use the Pythagoras theorem:
12^2 = 6^2 + h^2 where h is the height on the barn
h^2 = 12^2 - 6^2
h^2 = 144 - 36 = 102
h= √108 = 10.39

- Reading a Cartesian Plane
Step-by-step explanation:
When we label a Cartesian Plane, we label counterclockwise starting at the top right corner:
Top Right Corner = 1st Quadrant
Top Left Corner = 2nd Quadrant
Bottom Left Corner = 3rd Quadrant
Bottom Right Corner = 4th Quadrant
We see that point B is in the Bottom Right Corner. Therefore, it is in the 4th Quadrant and our answer would be D.
