Answer:

Step-by-step explanation:
Using Tangent Secant theorem:
(x)² = (2)(2+6)
x² = 2(8)
x² = 16
Equation in point slope form of a line:
y-y₀=m(x-x₀)
m=slope
(x₀,y₀)=(-4,7)
m=2/3
y-7=(2/3)(x+4)
Answer: y-7=(2/3)(x+4)
Answer:
x = 12
Step-by-step explanation:
__9x__ = __108___
9 9
x = 12
Answer:
10x - 5
Step-by-step explanation:
Perimeter is found by adding up all the side lengths.
(2x-4) + (5x+6) + (3x-7) = 10x - 5
