Will give bianleast 10 ponits

Which equation can be used to find the answer?

A fence with four sections has a perimeter of 43 ft. Three of the sections have lengths of 8 ft, 12 ft, and 11 ft. What is the length of the fourth section?

x = 43 + 8 + 12 + 11

x + 8 + 12 + 11 = 43

x - 8 + 12 + 11 = 43

x - 43 = 8 + 12 - 11

    x + 8 + 12 + 11 = 43

    Step-by-step explanation:

    The perimeter is the length of the 4 sections of fencing.

    If x represents the fourth section and the perimeter is 43, then

    x + 8 + 12 + 11 = 43, that is

    x + 31 = 43 (subtract 31 from both sides)

    x = 12

    The length of the fourth section is 12 ft
