Answer:
X=9
Step-by-step explanation:
Martys class has 30 dollars
Tommy has (6+x)X2=30
30/2 is 15
15-6 is 9
<h3>{ 13, 9, 6} represent the sides of a triangle</h3>
<em><u>Solution:</u></em>
<em><u>Use the triangle inequality law</u></em>
The sum of the lengths of any two sides of a triangle must be greater than the third side
<em><u>Option A</u></em>
{13, 9, 6}

Also,

Thus, sum of length of any two sides is greater than third side
Therefore, { 13, 9, 6} represent the sides of a triangle
<em><u>Option B</u></em>
{12, 7, 20}

19 is not greater than 20
Therefore, {12, 7, 20} does not represent the sides of a triangle
<em><u>Option C</u></em>
{25, 50, 75}

75 is equal to 75
Therefore, {25, 50, 75} does not represent the sides of a triangle
