    Would someone please be able to tell me the way to work out this question for full marks with working :

    The length in centimetres , of the sides of a quadrilateral are :

    2x x+6. 4x-12. 30-3x

    Explain why x must be greater than 3 and less than 10. Use the information to write an equation in terms of x (perimeter is 48cm)

    Length cannot be negative (or zero, otherwise it would be a triangle)

    so look at 4x-12 to get your minimum value for x

    and look at 30-3x to get your maximum value of x
