KLMN is the trapezoid. So:( KL + MN ) / 2 = HJ( 4 x + 1 + 27 ) / 2 = 5 x + 2 / * 24 x + 28 = 10 x + 410 x - 4 x = 28 - 46 x = 24x = 24 : 6x = 4KL = 4 * 4 + 1 = 16 + 1 = 17Answer: KL = 17
288 devided by 4 is 72
4 can go into 288 72 times
The third choice does not represent a proportional relationship because the y-intercept ≠ 0.
Hope that helped you.
