You just have to simplify:
-2n+6
Answer:
We can express the equation for any linear equation with slope -2 and point (x0,y0) as:

Step-by-step explanation:
Incomplete question:
There is no point to complete the equation.
As we have no point to complete the linear equation, we will solve for any given point (x0,y0) and a slope of m=-2.
The linear equation can be written generically as:

If a point, like (x0,y0) belongs to the linear equation, it satisfies its equation. Then:

Then, we can calculate b as:

We can express the equation for any linear equation with slope -2 and point (x0,y0) as:

Answer:
x=±
Step-by-step explanation:
Answer:
Area of shaded region=41 square feet
Area of non shaded region= 87 square feet
Step-by-step explanation:
As, Shaded area is made of different shapes including two rectangles and one triangle
So,
Area of shaded region,

Area of non shaded region=total area of rectangular region-Shaded region

Use Pythagorean Theorem:
a² + b² = c²
"a" is one side of the right triangle.
Its length is: radius of larger circle minus radius of smaller circle: (11 - 3 = 8)
The distance between the center of the circles creates the hypotenuse (17)
8² + b² = 17²
b² = 225
b = 15
Answer: the length of the common external tangent is 15.
