The second side of a triangular deck is 6 feet longer than the shortest side, and the third side is 6 feet shorter than twice the length of the shortest side. If the perimeter of the deck is 72 feet, what are the length of the three sides?

let the shortest side be 'x' ft

length of second side = x + 6 ft

length of third side = 2(x+6) - 6 ft

perimeter of triangle = 72 feet

shortest side + second side + third side = 72 ft

x + x + 6 + 2(x+6) - 6 = 72

4x + 12 = 72

x = 15

length of shortest side = 15 ft

length of second side = 15 + 6 = 21 ft

length of third side = 2(15 + 6) - 6 = 36 ft

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

the answer is b.
