 A. rhombus

Step-by-step explanation:

We know that a square is a quadrilateral with all sides equal in length . Also all  its interior angles are right angles.

Therefore, A square is always a rhombus.

A rhombus is not a square unless the angles are all right angles.

On the other hand a square is a rhombus since all four of its sides are of the same length.

Hence, A square is a type of a rhombus .

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
