Question

1. What is the perimeter of the figure below. Simplify.
4x^3-5x 2x^3+6x 6x^3+x

Answer 1

`12x^3+2x`

Explanation:

The perimeter of a polygon is equal to the sum of its sides.

The sides in the triangle shown have lengths
`2x^3+6x`,
`4x^3-5x`, and
`6x^3+x` in no specific order.

Since its perimeter is given by the sum of its sides, the perimeter is equal to:

`2x^3+6x+4x^3-5x+6x^3+x`

Combine like terms:

`\boxed{12x^3+2x}`
