Answer:
If AB is a tangent to the circle, the triangle ABO is right angled, as the angle where a tangent meets the circumference is always 90 degrees.
We also know that Pythogoras' theorem only holds for right angled triangles.
The hypotenuse is 12 + 8 as 12 is the radius so is 20.
16^2+12^2 = 256 + 144 = 400 = 20^2 so AB must be tangent.
If they have -8 points and +6 points, that'd leave them with a total of -2 points.
So the answer is -2.

Hello from MrBillDoesMath!
Answer:
sv = tu
Discussion:
For the case of a proportion the "cross product" refers to the products of the "extremes" equaling the products of the "means". As (s,v) are the extremes and (u.t) the means, this gives sv = tu
Thank you,

x is 
Step-by-step explanation:
Let us revise some rules of exponents
∵ 
- Factorize 27 and 9
∵ 27 = 3 × 3 × 3
∴ 27 = 3³
∵ 9 = 3 × 3
∴ 9 = 3²
Substitute them in the equation
∴ 
- Use the third rule to simplify each side
∴ 
- Use the fourth rule
∵ The bases of the two sides are equal
∴ Their exponents are equal
∴ 3x - 3 = 6x - 14
- Subtract 6x from both sides
∴ -3x - 3 = -14
- Add 3 to both sides
∴ -3x = -11
Divide both sides by -3
∴ x = 
x is
