Ann's first option is a plot of land adjacent to a current park.

oksian1 [2.3K]

Given:

The equation for the area of the first option is:

$x^2+200x=166400$

Where x is the side length of the current square park.

To find:

The side length of the current square park.

Solution:

We have,

$x^2+200x=166400$

It can be written as:

$x^2+200x-166400=0$

Splitting the middle term, we get

$x^2+520x-320x-166400=0$

$x(x+520)-320(x+520)=0$

$(x-320)(x+520)=0$

$x=320,-520$

We know that the side length of a park cannot be negative. So, the only possible value of x is 320.

Therefore, the most direct method to solve the given equation is splitting the middle term and the side length of the current square park is 320 meters.

Which situation demonstrates the law of large numbers

sveticcg [70]

Answer: Choice B

The more trials you do, the closer the empirical probability should get to the theoretical probability. It won't be a perfect match but it will likely be close enough so to speak. Note how 70/420 = 1/6.

Solve x:(x+4)/3=2<br> Will give points

sasho [114]

$\frac{x + 4}{3} = 2 \\ \\ \\ \text{ Multiply by 3 on both sides, }\\ \\ \\ = > \frac{x + 4}{3} \times 3 = 2 \times 3 \\ \\ \\ \\ = > x + 4 = 6 \\ \\ \\ = > x = 6 - 4 \\ \\ \\ = > x = 2$

Hence, value of x in the given equation is 2
