If the circumference of an isosceles triangle is 24, then the range of waist length x is -------- and the range of bottom edge y is -------

If the circumference of an isosceles triangle is 24, then the range of waist length x is -------- and the range of bottom edge y is -------


Waist length greater than 6 less than 12, bottom edge greater than 0 less than 12



If the width of the rectangle is 3A + 2B and the length is a more than the width, then the circumference of the rectangle is?


Perimeter = 2 (3a + 2B + 3A + 2B + a) = 14a + 8b;
