A trapezoid has four sides. The bottom base is three times the length of one of the diagonal sides. The top base is seven units less than the length of one of the diagonal sides. The diagonal sides are the same length. Write and simplify an expression to represent the perimeter of the trapezoid.

In Euclidean geometry, an isosceles trapezoid is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides. It is a special case of a trapezoid. Alternatively, it can be defined as a trapezoid in which both legs and both base angles are of the same measure.

Step-by-step explanation:

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
