Find the perimeter of a triangle with vertices A(3, 1), B(2, -1), and C(-3, 2). Leave

natulia [17]

The perimeter of triangle is: 14.15 units

Step-by-step explanation:

First of all we have to find the lengths of sides of triangles

Given

A(3, 1), B(2, -1), and C(-3, 2)

The distance formula will be used to find the lengths of sides

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

So,

$AB = \sqrt{(2-3)^2+(-1-1)^2}\\=\sqrt{(-1)^2+(2)^2}\\=\sqrt{1+4}\\=\sqrt{5}\\=2.24\ unitsBC = \sqrt{(-3-2)^2+(2+1)^2}\\=\sqrt{(-5)^2+(3)^2}\\=\sqrt{25+9}\\=\sqrt{34}\\= 5.83\ units\\AC = \sqrt{(-3-3)^2+(2-1)^2}\\=\sqrt{(-6)^2+(1)^2}\\=\sqrt{36+1}\\=\sqrt{37}\\=6.08\ units$

The perimeter of triangle will be:

$P = AB+BC+AC\\= 2.24+5.83+6.08\\=14.15\ units$

Hence,

The perimeter of triangle is: 14.15 units

Solve for x. Show each step of the solution. <br><br> 4(8-x)-32=98-5(3x+24)

Firlakuza [10]

Answer: x=−2

Step-by-step explanation:

Let's solve your equation step-by-step.

4(8−x)−32=98−5(3x+24)

Step 1: Simplify both sides of the equation.

4(8−x)−32=98−5(3x+24)

(4)(8)+(4)(−x)+−32=98+(−5)(3x)+(−5)(24)(Distribute)

32+−4x+−32=98+−15x+−120

(−4x)+(32+−32)=(−15x)+(98+−120)(Combine Like Terms)

−4x=−15x+−22

−4x=−15x−22

Step 2: Add 15x to both sides.

−4x+15x=−15x−22+15x

11x=−22

Step 3: Divide both sides by 11.

11x /11 = −22 /11

x=−2

A woman spent two thirds of her money she lost two thirds the remainder and then had $4 left how much money did she start with

Lisa [10]

Answer

Find out how much money did she start with.

To proof

let us assume that the money she had be x.

As given

woman spent two thirds of her money

$Money\ spent = \frac{2x}{3}$

Money she had after spent two thirds of her money = Total money - money spent

$= x - \frac{2x}{3}$

$= \frac{1x}{3}$

As given she lost two thirds the remainder

$=\frac{2}{3}\times ( money\ she\ had\ after\ spending\ two\ thirds\ of\ her\ money)$

$= \frac{2}{3} \times\frac{1x}{3}$

we get

$=\frac{2x}{9}$

Money she had after lost two thirds the remainder = Money she had after spent two thirds of her money - she lost two thirds the remainder

$= \frac{1x}{3} - \frac{2x}{9}$

$= \frac{1x}{9}$

As given

she had $4 left

thus

$\frac{1x}{9} = 4$

x = $36

she start with $36.

Hence proved
