The perimeter of a triangle is 56. The side lengths are x + 4, 3x + 7, and x + 9. What is the value of x?

Sidana [21]

<h3><u>Answer:</u></h3>

x = 7.2

<h3><u>Step-by-step explanation:</u></h3>

Perimeter: Side 1 + Side 2 + Side 3

=> 5x + 20 = 56

=> 5x = 56 - 20

=> 5x = 36

=> x = 7.2

<h3><u>Conclusion:</u></h3>

Therefore, the value of x is 7.2.
