The equations of four lines are given. Identify which lines are parallel. Line 1: y=12x−6 Line 2: x−2y=−1 Line 3: y=4x+6 Line 4: y+3=14(x−6)

An isosceles triangle has two sides of equal length, a, and a base, b. the perimeter of the triangle is 15.7 inches, so the equation to solve is 2a + b = 15.7. if we recall that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side, which lengths make sense for possible values of b? select two options.
