7.75 is the answerto the equation
2x - 4(x-4) = -2 + 3x + 3
2x - 4x + 16 = 3x + 1
-2x + 16 = 3x + 1
5x = 15
x = 3
Answer:

Step-by-step explanation:
Recall that the equation of a circle of radius R centered at
is given by:

For your particular case: R = 6,
= 2, and
= -5, therefore the equation becomes:

Answer:
? = 13.6
Step-by-step explanation:
the angle between a tangent and the diameter = 90°
Then the triangle is right with legs 2 × 6 = 12 and 6.4
using Pythagoras' identity in the right triangle.
the square on the hypotenuse is equal to the sum of the squares on the legs , that is
? ² = 12² + 6.4² = 144 + 40.96 = 184.96 ( take square root of both sides )
? =
= 13.6
