BD and AC are chords that intersect at point Y. A circle is shown. Chords B C and A C intersect at point Y. The length of B Y is

user100 [1]

Answer:

4 units

Step-by-step explanation:

we know that

The Intersecting Chord Theorem states that: When two chords intersect each other inside a circle, then the products of their segments are equal.

In this problem

$(BY)(YD)=(AY)(YC)$

substitute the given values

$(3)(8)=(x)(6)$

solve for x

$24=6x\\x=24/6\\x=4\ units$

therefore

The length of segment AY is 4 units

Can someone help me with this question

Mashcka [7]

The correct answer here would be D. -1(3x+1)(x+5). You can find this answer by redistributing the problem.

-1(3x+1)(x+5)
-1(3x²+15x+1x+5)
-1(3x²+16x+5)
-3x²-16x-5

Using the math above, we can see that when we redistribute we get the original equation. That makes Choice D correct.
