Question

32x - 12.8 simplify plz

Answer 1

`\boxed{8x-3.2}`

Explanation:

The perimeter is 32x - 12.8 of a square.

Use formula for perimeter of a square.

`P=4a`

`P=perimeter\\a=side \: length`

`32x - 12.8=4a`

Solve for side length.

`(32x - 12.8)/(4) =a`

`8x-3.2=a`

Three equivalent expressions for perimeter:

32x - 12.8

⇒ 8(4x - 1.6)

⇒ 4(8x - 3.2)

⇒ 2(16x - 6.4)

Answer 2

Length = 8x - 3.2

Explanation:

Perimeter = 4(Length) [Since it's a square so all the sides are equal]

Given that Perimeter = 32x - 12.8

32x - 12.8 = 4(Length)

Dividing both sides by 4

=> Length =
`(4(8x-3.2))/(4)`

=> Length = 8x - 3.2

Now, Three equivalent expressions to find the perimeter

=> Perimeter = 32x - 12.8

=> Perimeter = 4(8x - 3.2) [Perimeter = 4 (Length)]

=> Perimeter = 2(16x - 6.4)
