Question

Write an equation that you can use to find the value of x'.
Perimeter of triangle: 16 in.

Answer 1

x= 16/3

Explanation:

From the equation we know x is the same for all sides so the perimeter is:

p = x + x+ x we know the perimeter so it would be

16 = 3x (we add the x)

then we need to divide both sides by three to have an equation for x so it would be:

x= 16/3
