The length of each of the legs of an isosceles triangle is represented by the expression 5x - 2 inches.
The length of the base of the isosceles triangle is represented by the expression 3x + 1 inches.
The perimeter of the isosceles triangle is 42 inches.
Determine whether each equation represents the perimeter of the isosceles triangle, in inches.
Select ‘Yes’ or ‘No’ for each equation.
1. 13x - 3 = 42
2. (10x - 2) + (3x + 1) = 42
3. 2(5x - 2) + 2 (3x + 1) = 42
4. 5x - 2 + 3x + 1 + 5x - 2 = 42
