Answer:
x^2 + 6x + 2 = 0
Step-by-step explanation:
Just add 2 to both sides, obtaining x^2 + 6x + 2 = 0; this is in "general form" for a quadratic equation.
The answer is 201 because all you do is divide 1,005 by 5 then to check your answer you multiply 201 by 5 then you get 1,005.

Answer:
3,500,000/ 13
It means every 13 years it grows 3,500,000.
Step-by-step explanation:
The slope is a ration of the vertical distance to the horizontal distance between any two points on the line. This means count the up and down distance and the left and right distance between two points.
Find two points on the line that cross through the grid line intersections like here (200, 500,000) and (2013, 4,000000).
The vertical distance is 4,000,000 - 500,000 = 3,500,000.
The horizontal distance is 2013-2000 = 13.
Write a ratio or fraction between the two distances.
3,500,000/ 13
It means every 13 years it grows 3,500,000.
Answer:
x=35
Step-by-step explanation:
You just add up all of the equations to equal 180
X+20+x+8+2x+12=180
4x+40=180
4x=140
x=35
Answer:
x = 77°
Step-by-step explanation:
105° + x - 2 = 180°
103° + x = 180°
x = 77°
x - 2° would be the angle next to 100° because thy are corresponding.
Since in a line there is 180°, 105° + x - 2° is 180°
