4( x+6)=-4(2x-9)+3x​

Mathematics
1 answer:
kupik [55]3 years ago
4 0

Answer:

x=1.33 repeating or 1 1/3

Step-by-step explanation:

You take 4 and distribute to everything in the parentheses.

You also do the same for the -4.

After you distribute, you should get: 4x+24=-8x+36+3x

Then you combine like terms (the two x's on the right side of the equation.

You should then get: 4x+24=-5x+36

Next, you subtract 24 from the positive 24, to cancel it out, and the 36 to get 12.

Then, add 5x to the negative 5x, to cancel it out, and to the 4x to get 9x.

Finally, you divide 12 by 9 to get 1.33 repeating or 1 1/3.

A regular octagonal pyramid. Each side of the base is 6 cm long. it has a height of 10cm. Find the surface area of the pyramid​
attashe74 [19]

9514 1404 393

Answer:

  470.16 cm²

Step-by-step explanation:

The apothem of the base is used for two purposes: to find the area of the base, and to find the slant height of each face.

The apothem of the base for side length s is ...

  s/2 = a·tan(π/8)

  a = s/(2·tan(π/8)) ≈ 7.24 cm

The slant height of a triangular face is found using the Pythagorean theorem. The apothem of the base and the height are legs of the right triangle whose hypotenuse is the slant height. For slant height x, we have ...

  x² = 10² + a² = 100 +52.46

  x ≈ √152.46 ≈ 12.35

__

The area of the 8 triangular faces will be ...

  A = 1/2Px . . . . where P is the perimeter of the pyramid

The area of the base will be ...

  A = 1/2Pa

So, the total surface area is ...

  A = 1/2P(a + x) = (1/2)(8)(6 cm)(7.24 +12.35 cm) ≈ 470.16 cm²
