Question

Tell whether a triangle can have sides with the

given lengths. Explain, why or why not.
3x + 2, x?, and 2x when x = 4

Answer 1

`3x+2 \\e x^2 \\e 2x` for
`x = 4`

Explanation:

Given

Shape: Triangle

Dimension: 3x + 2, x^2 and 2x

`x = 4`

Required

Determine if it has equal sides

To do this, we simply substitute 4 for x in the given dimensions

3x + 2

`3x + 2 = 3 * 4 + 2`

`3x + 2 = 12 + 2`

`3x + 2 = 14`

x^2

`x^2 = 4^2`

`x^2 = 16`

2x

`2x = 2 * 4`

`2x = 8`

`3x+2 \\e x^2 \\e 2x` for
`x = 4`
