Answer: x = -54

Step-by-step explanation:

Simplifying

(2x) = (4x + 108)

Reorder the terms:

(2x) = (108 + 4x)

Remove parenthesis around (108 + 4x)

(2x) = 108 + 4x

Solving

(2x) = 108 + 4x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4x' to each side of the equation.

(2x) + -4x = 108 + 4x + -4x

Combine like terms: (2x) + -4x = -2x

-2x = 108 + 4x + -4x

Combine like terms: 4x + -4x = 0

-2x = 108 + 0

-2x = 108

Divide each side by '-2'.

x = -54

1. The perimeter of a piece of paper is 18 cm.

OlgaM077 [116]

Answer:

a) length = 3 and width = 6

Area of the rectangle = 3 × 6 = 18 cm²

b) length = 7 and width = 2

Area of the rectangle = 7 × 2 = 14 cm²

c) length = 5 and width = 4

Area of the rectangle = 5× 4 = 20 cm²

Step-by-step explanation:

Step(i):-

Given perimeter of the paper = 18 cm

we know that the paper has a rectangle shape

The perimeter of the rectangle = 18 cm

2( l + w ) = 18

we choose length = 3 and width = 6

The perimeter of the rectangle = 2( 3+6) = 18 cm

Area of the rectangle = 3 × 6 = 18 cm²

we choose length = 7 and width = 2

The perimeter of the rectangle = 2( 7+2) = 18 cm

Area of the rectangle = 7 × 2 = 14 cm²

we choose length = 5 and width = 4

The perimeter of the rectangle = 2( 5+4) = 18 cm

Area of the rectangle = 5× 4 = 20 cm²

(x + 1)2 + (y - 3)2 = 36 What is the radius?

NARA [144]

Answer:

Step-by-step explanation:

Any circle in the form

$(x+\alpha)^2 + (y+\beta)^2 = r^2$

Where r^2 is the radius squared, so

$r^2=36$

$r=6$

Need help with this!!!!!!!!

zzz [600]

The linear combination method is the same as the elimination method. Let's multiply the second equation by -2 so the x terms cancel each other out. When we do that we get a system of $2x-3y=13$ and $-2x-4y=8$ . The x-terms cancel each other out giving us $-7y=21$ and y = -3. Now sub -3 into one of the equations to solve for x. x+2(-3)=-4, and x - 6 = -4. x = 2. So the solution for our system is (2, -3)

Find an equation of the line that goes through the points (10,34) and (-1,10)

kotykmax [81]

Answer:

Given points are ( 10 ,34 ) and ( -1 , 10)

Step-by-step explanation:

The equation of line is given by 

first we can find slope (m) 

= (y2 - y1) / ( x2 - x1)

= 34-10/10+1

 =24/11

Now the equation is

y - y1 = m ( x - x1) 

y - 10 = 24/11 ( x +11)

11 ( y - 10 ) = 24 (x + 11)

11y - 110 = 24x + 264

24x + 264 +110-11y =0

24x - 11y + 374 = 0

which is the required equation
