Answer:

x = 18

Step-by-step explanation:

\frac{8}{12}  = \frac{12}{x}

  • then cross-multiply

8x = 12 * 12

8x = 144

\frac{8x}{8} = \frac{144}{8}

x = 18

Expand the polynomial and simplify: (4xy− 1 8 y^2)^2
Vinvika [58]

Answer: 4y^{2}(2x-9y)^{2}

Step-by-step explanation:

We have the following polynomial:

(4xy-18y^{2})^{2}

This is a polynomial of the form (a-b)^{2}=a^{2}-2ab+b^{2}. Following this rule to expand it, we have:

(4xy)^{2}-2(4xy)(18y^{2})+(18y^{2})^{2}

16x^{2}y^{2}-144xy^{3}+324y^{4}

Applying common factor 4y^{2}:

4y^{2}(4x^{2}-36xy+81y^{2})

Note the polynomial inside the parenthesis is a perfect square trinomial, which can be factored to(2x-9y)^{2}. Hence, the final simplification is:

4y^{2}(2x-9y)^{2}

ozzi

The percent change in attendance, relative to last year's show is a 5% increase.

<h3>What is a percentage? </h3>

A Percentage can be described as a fraction out of an amount that is usually expressed as a number out of hundred.

<h3>What is the percentage change in attendance? </h3>

The value of the percentage change in attendance can be determined by subtracting the number of people in this year's show from the number of people at last year's show. The result would be divided by the number of people at last year's show and multiplied by 100.

[(16,800 - 16,000)/16,000] x 100 = 5%
