Please help with geometry homework ! Mark brainliest
REY [17]

Theorem: If two chords intersect within a circle, then the product of the lengths of the segments (parts) of one chord is equal to the product of the lengths of the segments of the other chord.

In your case this theorem sounds as

2\cdot x=3\cdot 6.

Solve this equation:

x=\dfrac{3\cdot 6}{2}=9.

(-4+2i)(7-2i) <br> Anyone know how to do this??
avanturin [10]

Answer:

<h2>-24 + 22i</h2>

Step-by-step explanation:

Use the FOIL method of multiplication of binomials:

(-4+2i)(7-2i) = -28 + 14i + 8i - (-4)i²

Note that i² = -1.  Thus, - (-4)i² = +4, and we then have:

-28 + 22i + 4, or

-24 + 22i
