Question

the lengths of the sides of a triangle are consecutive odd integers. if the perimeter is 1 less than four times the shortest side, find the lenght of each side

Answer 1

(2x+1)+(2x+3)+(2x+5) = 4(2x+1)-1


2x+1+2x+3+2x+5 = 8x+4-1



6x+9=8x+4-1



6x+9=8x+3



6x=8x+3-9



6x-8x=3-9



-2x=3-9



-2x=-6



x=-6/(-2)



x=3



So the three side lengths are

2(3)+1 = 6+1 = 7

2(3)+3 = 6+3 = 9

2(3)+5 = 6+5 = 11

Answer 2

thanks but how did you get 2x

Answer 3

nevermind i got it
