Answer:
6xy²+7-x²y²-5x²y+3x²y²=6x²+7+2x²y²-5x²y
Answer:

Step-by-step explanation:
If AB is tangent to the circle, then angle ABO is right angle and triangle AOB is special
triangle. In this triangle, the leg that is opposite to the angle of 30° is half of the hypotenuse. Thus,

By the Pythagorean theorem,

Answer: It would be option B (13 over 5).
Step-by-step explanation: Step 1) Subtract 15 from both sides, 5x=13. Step 2) Divide both sides by 5, x=13 over 5. Hope this helps bub <3
Answer:
Step-by-step explanation:
(1860-11)=1849
√(1849) = 43
(A quick trial)
AB + C
= (x + 1)(x^2 + 2x - 1) + 2x
= x^3 + 2x^2 - x + x^2 + 2x - 1 + 2x
= x^3 + 3x^2 + 3x - 1
