Answer:

x=10

Step-by-step explanation:

7\left(3x-1\right)-6\left(2x+3\right)=8\left(x-2\right)+1

7\left(3x-1\right)-6\left(2x+3\right)

<u>Expand, using Distributive law:</u>

<u />7\left(3x-1\right)

  • 21x-7

____________

-6\left(2x+3\right)

  • -12x-18

_____________

8\left(x-2\right)+1

  • 8x-16+1
  • -16+1=-15
  • 8x-15

______________

21x-7-12x-18

<u>Combine like terms:</u>

<u />9x-25

9x-25=8x-15

<u>Add 25 to both sides:</u>

<u />9x-25+25=8x-15+25

9x=8x+10

<u>Subtract 8x from both sides:</u>

<u />9x-8x=8x+10-8x

x=10

Step-by-step explanation:

Use the surface area formula with the given numbers.

  SA = 2(LW +H(L +W))

  SA = 2(12·6 +9.5(12 +6)) = 2(72 +9.5(18)) = 486

The surface area of the box is 486 square units.

Complete the square to rewrite x^2+y^2+2x+6y-6=0 in graphing form
Ksivusya [100]

Answer:

(x + 1)² + (y + 3)² = 16

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Given

x² + y² + 2x + 6y - 6 = 0

Collect the x and y terms together and add 6 to both sides

x² + 2x + y² + 6y = 6

To complete the square

add ( half the coefficient of the x/ y terms )² to both sides

x² + 2(1)x + 1 + y² + 2(3)y + 9 = 6 + 1 + 9

(x + 1)² + (y + 3)² = 16

with centre = (- 1, - 3) and r = \sqrt{16} = 4
