The description for an Isosceles trapezoid is that it has two opposites parallel, the two other opposites legs are equal and also the diagonals are equal. side 1 = AB = 6y-6 side 2 = BC = 4y -7 side 3 = CD = 7y-12
When AB & CD are the two opposites and their measurement are equal. We will be we have: AB=CD 6y-6 = 7y -12 Perform transposition method: 7y-6y=12-6 1y = 6 y=6
The inequality would be the negative factor, because -5n+2n is 3n. You would write it on a number line like this..... Sry, i was just making an educated guess.... RIP....
