Divide by greatest common factor.
Answer simplified should be 6y(4x^2-1)
Rewrite in the form where a^2-b^2
Answer
6y(2x+1)(2x-1)
<u>Given:</u>
The circle has a diameter of 30 cm and a chord of 10 cm is drawn.
Radius of the circle = 15 cm
Half of the chord = 5 cm
We need to determine the distance of chord from the center of the circle.
<u>Distance of chord from the center of the circle:</u>
Let us use the Pythagorean theorem, to find the distance between the center and the chord.
Let d denote the distance between the center and the chord of the circle.
Thus, we get;



Taking square root on both sides, we get;

Thus, the distance between the center and the chord of the circle is 14.14 cm.
Hence, Option A is the correct answer.
Answer:
$41.31
Step-by-step explanation:
45 times 0.15 = 6.75
45 - 6.75 = 38.25
38.25 times 1.08 = 41.31
Answer will be 1 or 20+14 root 2/1+11 root 2
