Question

work out the perimeter of the triangle when the sides are : 3x-5 2x 19-x

Answer 1

Answer:

4x + 14

Step-by-step explanation:

The perimeter of the triangle is equal to the sum of its three sides.

The sides of the triangle are 3x-5, 2x, and 19-x.

Calculate their sum.

3x - 5 + 2x + 19 - x

Rearrange.

3x + 2x - x + 19 - 5

Add or subtract like terms.

4x + 14

The perimeter of the triangle is 4x + 14.

Answer 2

Answer:

The perimeter of the triangle is 4x+14

Step-by-step explanation:

Perimeter is sum of all sides.

So,

=> 3x-5+2x+19-x

=> 5x-x-5+19

=> 4x+14

So, The perimeter of the triangle is 4x+14
