Answer:
The perimeter of the triangle is 4x+14
Step-by-step explanation:
<u><em>Perimeter is sum of all sides.</em></u>
So,
=> 3x-5+2x+19-x
=> 5x-x-5+19
=> 4x+14
So, The perimeter of the triangle is 4x+14
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.
