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.

HELP!!!!!!!!!! PLEASE!!!!!!!WILL MARK AS BRAINLIEST
Goshia [24]

<t =33 since triangle  RUT is isosceles  (RU = TU)

<r + <u + <t = 180  triangle = 180

33 + <u + 33 = 180

66 + <u = 180

< u =114

<rus = < sut  from the diagram

<rus + <sut = <u

x + x = 114

2x = 114

divide by 2

x = 57

How to factor 4x^2+7x-15
GuDViN [60]
4x^2+7x-15

Break the expression into group:

(4x^2+5x)+(12x-15)

factor out x from 4x² - 5x : x (4x-5)
factor out 3 from 12x-15 : 3 (4x-5)

=x(4x-5)+3(4x-5)

factor out common term (4x-5) :

= (4x-5)(x+3)

hope this helps!
