Question

The

largest side of a triangle is six more units than the smallest side.  The third side is twice the smallest
side.  If the perimeter of the triangle
is 25 units, write and solve an equation to find the lengths of all three sides
of the triangle. 

Answer 1

To verify your final answer:

x = 4.75

2x = 9.5

x+6 = 10.75

Explanation:

Let X = the length of the shortest side

Then the longest side is X + 6 and the other side is 2X.

The sum of all sides equals the perimeter which equals 25.

So add them up, set it equal to 25 and solve for X.

Answer 2

x+6+x+2x=25, x being the smallest side
