2x*2=14x-20 <span>Simplifying 2x * 2 = 14x + -20 Reorder the terms for easier multiplication: 2 * 2x = 14x + -20 Multiply 2 * 2 4x = 14x + -20 Reorder the terms: 4x = -20 + 14x Solving 4x = -20 + 14x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-14x' to each side of the equation. 4x + -14x = -20 + 14x + -14x Combine like terms: 4x + -14x = -10x -10x = -20 + 14x + -14x Combine like terms: 14x + -14x = 0 -10x = -20 + 0 -10x = -20 Divide each side by '-10'. x = 2 Simplifying x = 2

Best of luck hope I helped :)

-4x-2 = -2(1-4x)

-4x-2 = -2 + 8x

-2 = -2 + 12x

0 = 12x

x = 0

Anika is hiking on a rectengular trail at the nation park there are four resting spots along the corners of the trail on the map

Answer:

The perimeter is 14 units

<em></em>

Step-by-step explanation:

Given

$A = (-2,2)$

$B = (1,2)$

$C = (1,-2)$

$D = (-2,-2)$

Required

Determine the perimeter

To do this, we simply calculate the distance between the sides of the rectangle i.e. AB, BC, CD and DA.

Distance (d) is calculated using:

$d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}$

For AB

$A = (-2,2)$ --- $(x_1,y_1)$

$B = (1,2)$ --- $(x_2,y_2)$

$AB = \sqrt{(-2 - 1)^2 + (2 - 2)^2} = \sqrt{9} = 3$

For BC

$B = (1,2)$ --- $(x_1,y_1)$

$C = (1,-2)$ --- $(x_2,y_2)$

$BC = \sqrt{(1-1)^2 + (2--2)^2} = \sqrt{16} = 4$

For CD

$C = (1,-2)$ --- $(x_1,y_1)$

$D = (-2,-2)$ --- $(x_2,y_2)$

$CD = \sqrt{(1 - -2)^2 + (-2 -- 2)^2} = \sqrt{9} = 3$

For DA

$D = (-2,-2)$ --- $(x_1,y_1)$

$A = (-2,2)$ --- $(x_2,y_2)$

$DA = \sqrt{(-2--2)^2 + (-2-2)^2} = \sqrt{16} = 4$

So, the perimeter (P) is:

$P = AB + BC + CD + DA$

$P = 3 +4 + 3 + 4$

$P = 14$

<em>The perimeter is 14 units</em>
