One side of a triangle is 2 times the second side. the third side is 5 ft longer than the second side. the perimeter of a triangle is 81 ft. find the length of each side.
well if he used 15 in 2 says thats saying he used 7.5 a day and 7.5 times a year 365 days would be 2737.5
is that all to the question
step-by-step explanation: x is an even number. x+2 is the next even number, x+4 is the third even number in the set, x+6 is the fourth, x+8 is the fifth. x+x+2+x+4+x+6+x+8=100. so 5x+20=100. 100-20=5x+20-20. 80=5x. x=16.
