Answer:
11. x = -3+√37 ≈ 3.08276
12. x = 11.2
13. x = -6 +6√5 ≈ 7.41641
Step-by-step explanation:
In each case, the relation of interest is ...
(distance to circle near) × (distance to circle far) = (distance to circle near) × (distance to circle far)
When there is only one point of intersection of the secant with the circle—because it is a tangent—then the product is the square of the length of the tangent.
11. 2(2+12) = x(x +6)
x² +6x -28 = 0
(x +3)² -37 = 0
x = -3+√37 ≈ 3.08276
12. 5(5+x) = 9(9)
5x +25 = 81
x = 56/5 = 11.2
13. x(x +12) = 12(12)
x² +12x -144 = 0
(x +6)² -180 = 0
x = -6 +√180 ≈ 7.41641

<em>Comment on this secant rule</em>
This rule turns out to apply whether the point of intersection of the secant lines is outside the circle (as in these problems) or inside the circle (as in problem 9). The product of the two distances from the point of intersection to the circle is a constant for a given pair of intersecting secants/chords.
No
compare x+3 with (x-a)
you get a as -3
replace -3 with x in the function and if it equals to zero, then x+3 will be a factor but if not, then its not a factor

<h3>What is an Inequality ?</h3>
The statement formed when two algebraic expressions are equated by an inequality operator is called an Inequality.
The inequality given that
k > - 8 + 3
k > -5
As k is greater than -5 so k = -1 and k = 0
Therefore Option D , E is the right answer.

Answer:
y = 3x - 5
Step-by-step explanation:
So first take any two points from the graph.
(0, -5), (2, 1)
The slope is 
y = mx + b
b is the y intercept
The y intercept is (0, -5) as this is where the line intersects the y axis.
y = 3x - 5
