Which equation can be used to find the answer? A playground with four sides has a perimeter of 73 ft. Three of the sides have lengths of 14 ft, 19 ft, and 25 ft. What is the length of the fourth side?
s – 14 – 19 – 25 = 73Â
s – 73 = 14 + 19 – 25Â
s – 14 + 19 + 25 = 73Â
s + 14 + 19 + 25 = 73Â
Which is not a valid way to determine the perimeter of a rectangle with side lengths of 18 inches and 22 inches?
PÂ = 2(18) + 22
PÂ = 2(18) + 2(22)
PÂ = 18 + 22 + 18 + 22
PÂ = 2(18 + 22)
