Is segment AB tangent to circle O shown in the diagram, for AB = 10, OB = 5, and AO = 14. Explain your reasoning and show all work in your own words. (The figure is not drawn to scale.) Thank you!

(-0, -7) is your answer

Ive seen this before! the answer is b

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
