Answer:

18x - 36

Step-by-step explanation:

In an equilateral triangle the 3 sides are congruent, then

perimeter = 6x - 12 + 6x - 12 + 6x - 12 ← collect like terms

                = 18x - 36

The required expression would be 18x - 36 for the perimeter of the triangle in simplest form.

The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations is called the arithmetic operator.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

As we know in an equilateral triangle the 3 sides are congruent.

The perimeter of the triangle = 6x - 12 + 6x - 12 + 6x - 12

Combine the likewise terms and we get

The perimeter of the triangle =  18x - 36

Therefore, the required expression would be 18x - 36 for the perimeter of the triangle in simplest form.

Answer:

x=27

Step-by-step explanation:

Step 1: Multiply both sides by 5.

4(x−2)

5=20

(4(x−2)*(5)*(5)=(20)*(5)

4(x−2)=100

Step 2: Simplify both sides of the equation.

4x−8=100

Step 3: Add 8 to both sides.

4x−8+8=100+8

4x=108

Step 4: Divide both sides by 4.

4x/4=108/4

x=27

Step-by-step explanation:

(x-2)/5 = 5

(x-2) = 25

Answer:

[tex]x=9, AB=BC=AC=35[/tex]

Step-by-step explanation:

Equilateral triangles have 3 congruent sides, so all 3 sides have the same length. Therefore, we know that [tex]AB=BC=AC[/tex]. We are given the lengths of all 3 sides in terms of [tex]x[/tex], but we only need to set two of them equal to each other to solve for [tex]x[/tex]. Let's use [tex]AB[/tex] and [tex]BC[/tex] to solve for [tex]x[/tex]. We know that [tex]AB=BC[/tex], [tex]AB=2x+17[/tex], and [tex]BC=6x-19[/tex]. Therefore, we can write the following equation to solve for

[tex]AB=BC\\2x+17=6x-19[/tex] (Substitute given values into equation)

Solving for [tex]x[/tex], we get:

[tex]2x+17=6x-19\\2x+17-17=6x-19-17[/tex] (Subtract [tex]17[/tex] from both sides of the equation to isolate constants)

[tex]2x=6x-36[/tex] (Simplify)

[tex]2x-6x=6x-36-6x[/tex] (Subtract [tex]6x[/tex] from both sides of the equation to isolate [tex]x[/tex])

[tex]-4x=-36[/tex] (Simplify)

[tex]\frac{-4x}{-4}=\frac{-36}{-4}[/tex] (Divide both sides of the equation by [tex]-4[/tex] to get rid of [tex]x[/tex]'s coefficient)

[tex]x=9[/tex] (Simplify)

Therefore, [tex]AB=2x+17=2*9+17=18+17=35[/tex], and [tex]AB=BC=AC=35[/tex]. Hope this helps!  

Answer:

x = 15/14

Step 4: Divide both sides by 7.

Answer:

68

Step-by-step explanation:

The formula for finding the are of a right triangle is

A= 1/2bh

( area = base times height divided by 2)

17 is the base and 8 is the height, 8*17=136

136÷2=68

Answer:

Kristen bought 2 fancy shirts and 5 plain t-shirts.

Step-by-step explanation:

Given that,

Kristen spent $131 on 7 shirts.

Cost of one fancy shirt = $28

Cost of one plain t-shirt = $15

Let,

x be the number of fancy shirts

y be the number of plain t-shirts

x+y = 7       Eqn 1

28x+15y=131    Eqn 2

Multiplying Eqn 1 by 15

15(x+y=7)

15x+15y=105    Eqn 3

Subtracting Eqn 3 from Eqn 2

(28x+15y)-(15x+15y)=131-105

28x+15y-15x+15y=26

13x=26

Dividing both sides by 13

[tex]\frac{13x}{13}=\frac{26}{13}\\x=2[/tex]

Putting x=2 in Eqn 1

2+y=7

y=7-2

y=5

Hence,

Kristen bought 2 fancy shirts and 5 plain t-shirts.

Answer:

Answer:

x=-2 and y=-3

Step-by-step explanation:

2x+4y=-16

-2(-2x+2y=-2)

2x+4y=-16

4x-4y=4

6x=-12

x=-2

2x+4y=-16

2(-2)+4y=-16

-4+4y=-16

+4        +4

4y=-12

y=-3

Answer:

x=-2

y=-3

Step-by-step explanation:

2x=-4y-16 subtract 4y and move to the other side of the equation

x=-2y-8 divide by 2 to isolate x

-2(-2y-8)+2y=-2 plug x into the second equation

4y+16+2y=-2 distribute

6y=-18 combine the Y's and subtract 16 to the other side

y=-3 divide both sides by 6

2x+4(-3)=-16 plug the y value into the first equation to find x

2x-12=-16 distribute (multiply)

2x=-4 add 12 to both sides

x=-2 divide by 2 to get the x value
