A triangle has one side that measures 12, another side that measures x, and a third side that measures 4 less than x. The perimeter is 26. Which equation would we use to find the value of x?

x + x + 4 + 12 = 26

x + x - 4 + 12 = 26

x + x - 4 = 26

x + x + 4 = 26

Perimeter = sum of all 3 sides in a triangle

so

x + x - 4 + 12 = 26

answer

B. x + x - 4 + 12 = 26
