5. a triangle aabc on h has all sides of length s (so is equilateral). let the incircle of triangleabc have inradius r. what is the range of possible values for cosh r? s

Given: hf || jk; hg ? jg prove: fhg ? kjg to prove that the triangles are congruent by asa, which statement and reason could be used as part of the proof? fgh ? kgj because vertical angles are congruent. jkg ? hfg because vertical angles are congruent. fhg ? jkg because right angles are congruent. hfg ? kjg because alternate interior angles are congruent.

Polynomial that can be factored as (3x-4)(3x+4)

2x minus y equals 6, x plus y equals negative 3
