Answer:
Step 1:
We need to place the numbers in descending order of the power. Here, has the largest power, so that number goes first. We keep doing this until we end up with our final expression, placed in order based on the powers.
Step 2:
We can see that the last three numbers, 17, -7, and 6, don't have variables or powers, so we simplify by adding (and subtracting) them.
Our final equation:
Answer:
30 in
Step-by-step explanation:
See attached image.
The length of AB is 17 (radius). The length of AC is 8 (given info).
AC splits segment BD in half, so point C is the midpoint of segment BD.
AC is perpendicular to the chord, so triangle ABC is a right triangle. You now have a right triangle with a leg of length 8 and hypotenuse of lenght 17.
The Pythagorean Theorem: (leg)^2 + (leg)^2 = (hypotenuse)^2.
That's half the length of the chord, so double that to get 30 inches for the full length of the chord BD.
