10x - 10 < -50 Add 10 to both sides of the inequality 10x -10 + 10 < -50 + 10 10x < -40 Divide both sides by 10 x < -4
In an Equilateral triangle, all 3 sides are equal. Therefore AB = BC = CA So, 3x = 2x + 12 Subtract 2x from both sides of the equation 3x - 2x = 2x + 12 - 2x x = 12 Therefore AB = 3x = 3 x 12 = 36 Perimeter = AB + BC + CA = 3AB = 3 x 36 = 108
