If you expand the entirety of the polynomial, you get the following:

32x^5+80x^4y+80x^3y^2+40x^2y^3+10xy^4+y^5

Answer:

Option B. The value of x is 20

Step-by-step explanation:

we know that

<u>The intersecting chords theorem</u> states that the products of the lengths of the line segments on each chord are equal.

In this problem

$(x)(x-11)=(x-8)(x-5)\\x^{2}-11x=x^{2}-5x-8x+40\\-11x=-13x+40\\2x=40\\x=20$
