If y is inversely proportional to the square of (3x + 2) and y= 4 when x=2/3, find y when x= 11 1/3,

Step-by-step explanation:

i hope i didnt answer too late i see that ot says 7 min remaining but oh well  

the answer

equation: (7x-13)+(x+29)+(3x + 5) = 180    (the reason why i put = to 180 is because every triangle adds up to 180 degrees)

first of all add the numbers: 29-13+5 = 21--- then add variables: 7x+3x+x= 11x

you get ur equation as: 11x  + 21 = 180--- 180-21=11x---159=11x--- 159/11=14 9/20

x = 14 9/20 permiter = 88.15 + 43.45 + 48.35 = 179.95

really hope this helps :) good luck
